2 Descriptive Annex 1 INTRODUCTION This pattern is a meter measuring system inclusive of a product return system fitted to a road tanker for the transport and delivery of liquids with low viscosity stored at atmospheric pressure. It comprises a multi-compartment tank, an optional multi-compartment manifold pipe and valve system, an optional pump fitted with a pneumatic relief valve, filters, a meter, a special gas extractor, a full hose reel, a bulk delivery line, selector valve and compatible ancillary equipment. A product return system is fitted complete with non return valves, guard bar assembly and interlock system. The system allows: (a) (b) (c) (d) (e) metered delivery by pumping (full hose) metered delivery by pumping (empty hose) direct delivery, with or without pumping, without passing through the meter. unlimited product return, including transfer of product from one compartment to another. self loading without passing through the meter. The hydraulic system is shown in Figures 1 and 2 which is followed by a key (Figure 4). 2 CONSTRUCTION 2.1 Mechanical Hydraulics The hydraulic system is shown in Figures 1 and 2. Liquid may flow from any of the selected compartments of the cargo tank via the appropriate foot valve and manifold valve into the manifold. From there it passes through an electronically controlled special gas extractor SgP which is fitted within the manifold which in turn acts as the outlet from the manifold into the pump suction pipe. The liquid then passes through an optional flexible coupling or hose into a cargo pump fitted with a pneumatically operated relief valve P, PRv. From there it passes through an optional 2 way valve R2 which allows a metered delivery or un-metered bulk delivery. Metered deliveries pass through an optional filter, meter C, flow sensing valve FSv, system isolation valve PIV, 2 way valve which allows full hose or empty hose delivery R3, hosereel FH1, hose and trigger nozzle cla Special gas extractor A schematic is shown in Figure 3. This is a form of special gas extractor manufactured by Mechtronic Ltd type MF400. The MF400 consists of a housing optionally secured between two manifold valves thus forming part of the manifold pipe. The housing is closed off by a housing lid. The MF400 contains an optic detector probe, S1, a microprocessor controlled vent valve, T3, and a fitting used to connect an optional manifold balance pipe. The housing also provides for a second optic probe, S2, fitted into the lower part of the housing just prior to the outlet flange. 2
3 Both top and bottom probes, S1 and S2, are connected to the special gas extractor electronic control unit, CU. The special gas extractor electronic control unit converts the signals received from the optic probes into pneumatic/electrical signals controlling the pneumatic relief valve, PRv, on the pump, the system isolation valve, PIV, and the gas extractor vent valve, T3. Gas from the MF400 is vented, via a valve, controlled by the special gas extractor electronic controller, into a liquid collection tank, T1. The collection tank is vented to atmosphere and is fitted with a drain valve, Dv Meter This is a Tuthill Transfer Systems FPP Meter Division positive displacement meter, approved by EEC certification No UK The pattern is a rotary positive displacement type meter with two oval gear rotors. Optionally, any suitable approved meter type may be used Meter head assembly The meter head assembly comprises of the following Veeder-Root equipment (a) Counter VR 7887XX-XXX (b) Ticket printer VR 7888XX-XXX (c) Preset VR XXX (d) Counter/printer VR 7890XX-XXX (e) Register/Preset/Printer VR78920X-XXX Pump This pattern will accept any Pump fitted with a pneumatically operated relief valve capable of producing the required minimum and maximum flow rates and pressures. 2.2 Electronics Veeder-Root EMR 3 Electronic register (Figure 10) The Veeder-Root EMR 3 electronic register head is mounted in the control cabinet and it receives pulses from an encoder mounted directly on the meter. These pulses are processed and connected via cable to the EMR 3 interconnect box (usually in the cab) which contains control and calculation functions and which interfaces with the printer Interlock functions are maintained and a ticket must be printed before the next transaction can start Software The software edition status of the EMR 3 is displayed upon switch-on. The software version number are: a) Register Head b) Interconnect Box The legally relevant software is represented by the last section (001) in the above version numbers and may not be changed without the prior approval of the National Weights and Measures Laboratory.
4 Note: Refer to the Setup and Operation manual for information on accessing the version number. When switched on, the EMR 3 software edition number is momentarily displayed on the Register head as F04 or any progressive increase in this letter or number Software security Recalibration and the amendment of calibration constants, labels, etc, may only be done when the EMR³ Register head is in the calibration control (C&C) mode. The C&C mode is accessible on the front panel of the display unit. To prevent unauthorised adjustment, a metal knurled threaded cover is screwed over the adjustment control. This cover is secured in position by passing a sealing wire through a pre-drilled hole in the cover and running it via pre-drilled holes in the heads of two adjacent panel securing screws. The wire ends are drawn taught and sealed with an approved seal Calibration factor Calibration is effected in the C&C mode and may be performed manually or automatically. Additionally, calibration may be carried out at each of 8 different flow rates. The number entered scales the pulses for the volume metered. After calibration, this number cannot be altered without breaking the seal on the Register Head Special gas extractor The special gas extractor electronic control unit houses both the electronic control module and solenoid operated pneumatic valves in the one housing. The front cover of the housing allows viewing of the status LEDs. The LEDs give the operator a real time status of the special gas extractor s optic probes and the open closed status of the special gas extractor vent valve, the pump relief valve and the system stop start valve. The software version number (1.1) is displayed through the front panel. Access to the software is limited either by the manufacturers security device or (on later manufacture) by potting the device and by the omission of any programming interface port thus precluding any change to the software Power supply The special gas extractor electronic control is powered by the vehicle battery. In the event of a power failure all pneumatic valves fail in the normally closed state thus stopping the delivery. The delivery can not be restarted until power is reinstated. The special gas extractor electronic control unit is optionally switched on and off by a pressure switch connected to the power take off pneumatic engagement signal. 2.3 Product return The system is designed to allow product to be returned to a compartment to permit the changeover of product following the completion of a delivery, but to inhibit product return until the ticket from that delivery has been withdrawn Hydraulics The system is shown in Figures 1 and 2, which is accompanied by a key in Figure 4. A general view is shown in Figure 6.
5 3 PERIPHERAL DEVICES AND INTERFACES 3.1 Interfaces The instrument may have the following interfaces: (a) Interconnection box (RS 485) (b) Quadrature pulse input (5V TTL logic) The Interconnection Box has the following interfaces: (a) Register head (RS 485) up to two possible from one IB (both with intrinsically safe supply) (b) Printer (RS 232) (c) 12 or 24 volt power supply 3.2 Peripheral devices The printer is typically an Epson TM-U295 slip printer. It is used for printing delivery tickets showing the date and time of a delivery, the ticket number, the quantity delivered, the price and other operator entered details. The nature and format of the ticket record is set up using the Register menu system. Any simple recipient printer may be used in place of the Epson TM-U295 printer provided: (i) (ii) it bears the CE mark for conformity to the EMC Directive 89/336/EEC; it is not capable of transmitting any data or instructions into the EMR³ other than for releasing the printout, checking for correct data transmission; (iii) it prints delivery results and other data as received from the EMR³ without any modification or further processing. 4 TECHNICAL DATA Technical data 80 mm system unit Nominal bore: 50 and 80 mm Maximum rate of flow: 800 litres / minute Minimum rate of flow: 150 litres / minute Maximum working pressure: 8 bar Minimum delivery Hose: 200 litres Minimum delivery Bulk: 1000 litres Liquids measured: liquids other than water of low viscosity (<20mPa.s) except liquefied gasses Climatic environment: -10 C to +40 C Open, condensing Electromagnetic environment: E3 Mechanical environment: M2 (vehicle mounted) Accuracy class: 0.5 Note: The maximum rate of flow, however, must not be greater than the maximum rate of flow of any component of the system.
6 5 OPERATION 5.1 Description The system allows pumped metered deliveries through the full hose reel and empty bulk discharge hose, pumped un-metered deliveries and optional un-metered self loading. Metered deliveries. The direction of flow is controlled by a pneumatically operated 2 way valve R3, directing flow to either the full hose or empty hose delivery system. Interlocks are provided to ensure that the 2 way valve R3 if operated during a delivery will cease the delivery. After completion of an empty hose delivery the hose is cleared of product by introducing compressed air into the system from air tank AT via blow down valve Bd. Sight glass Sg, provides indication of an empty hose. Un-metered deliveries. The direction of flow is controlled via a manual 2 way valve R2 situated between the pump and meter. Movement of this valve during a metered delivery will have no effect upon the integrity of the metered delivery. Once liquid has passes the meter there are no other possible outlets other than the hose end nozzle or the empty bulk hose. Optional self loading of the vehicle is permitted as the auxiliary suction is taken from the manifold which is situated upstream of the special gas extractor. When in self loading mode the special gas extractor is shut down thus closing the product isolation valve. No metered deliveries can be made whilst the external suction valve is open. The pneumatic and electronic circuitry has been designed on a fail safe principle, such that in the event of pneumatic failure, disconnection or electrical failure then the system will shut down Veeder-Root mechanical head assembly Metered delivery is set up by selecting the product and thus the compartment to be opened. The power take off is engaged energising the manifold control system and special gas extractor control unit. The manifold valve is then opened. The 2 way valve R2 is set for metered delivery and then the 2 way valve R3 is set for either full hose or empty hose delivery. If a preset delivery is required then the meter preset is set. A ticket is inserted into the meter and the meter preset valve is opened. Once the hose end nozzle is opened the delivery will commence. The special gas extractor will control the rate of flow via the pump relief valve and the product isolation valve during the delivery ensuring that no air/gas can leave the special gas extractor during the delivery. At the completion of the delivery the ticket is printed and the system shut down Veeder-Root EMR 3 electronic register Metered delivery is set up by selecting the product and thus the compartment to be opened.. A ticket is inserted into the ticket printer. The power take off is engaged energising the manifold control system and special gas extractor control unit. The manifold valve is then opened. The 2 way valve R2 is set for metered delivery and then the 2 way valve R3 is set for either full hose or empty hose delivery. If a preset delivery is required then the EMR 3 electronic register preset is set and the meter preset valve is opened. Once the hose end nozzle is opened the delivery will commence. The special gas extractor will control the rate of flow via the pump relief valve and the product isolation valve during the delivery ensuring that no air/gas can leave the special gas extractor during the delivery. At the completion of the delivery the ticket is printed and the system shut down.
7 Each ticket is sequentially numbered, indicates the quantity of liquid fuel delivered in each transaction and is issued at the point of delivery. 5.2 System incorporating product return Operation - mechanical meter head Normal delivery At the start of a delivery when the ticket is inserted and the printer handle is operated, the ticket is positioned by a slider and locked in place by a retaining pin that passes through a punched hole in the ticket. Closing the slide blocks the pneumatic signal to the product isolation valve PIV (Figure 1) rendering it closed. With the product return guard bar in its closed position a cam within the product return arm operates pneumatic valve GbV (Figure 1) sending a pneumatic signal to the product isolation valve thus opening the valve. Delivery is carried out normally. On completion, the printer handle is operated to print and releases the ticket Product return For product changeover, the mechanical catch holding the product return bar in its closed position is released and the product return guard bar raised, the wet-hose nozzle is then connected to the product transfer spout, which incorporates a non-return valve. Once raised, the pneumatic valve GbV actuated by the product return arm cam shuts off the pneumatic signal to the product isolation valve PIV rendering the valve closed. If a ticket is still in the printer then the printer handle is operated to print and release the ticket from the previous delivery. This opens PrV and sends a pneumatic signal to the product isolation valve PIV thus opening the valve. The quantity of product to be returned is entered on the pre-set device and pumping is started. When the product return is complete, the meter pre-set shuts off product flow and the hoseend nozzle is manually closed. The blowdown valve Bd is manually opened. This allows compressed air from the air tank AT to purge product from the bottom-loading pipework from Pt back into the compartment. Duration is approximately 2-5 seconds. The hose end nozzle is then removed from the product return spout, the product return guard bar lowered into its rest position which then deactivates the product return system Security features and interlocks If, during a normal delivery, the product return guard bar is raised, the presence of a ticket in the printer releases the pneumatic signal to the product isolation valve PIV and stops the flow of product If a ticket is inserted into the printer during the product return operation, the pneumatic signal from PrV to the product isolation valve PIV will be lost. This will close the product isolation valve PrV and product transfer will cease Product cannot be diverted into a compartment via a product transfer connector during a normal delivery because the raising of the product return guard bar causes the product isolation valve PrV to close and flow will cease.
8 5.2.3 Operation - electronic meter head - EMR For product changeover, the mechanical catch holding the product return bar in its closed position is released and the product return guard bar raised, the wet-hose nozzle is then connected to the product transfer spout, which incorporates a non-return valve. Once raised, the pneumatic valve GbV actuated by the product return arm cam sends a signal to a pressure switch which identifies to the system that product transfer is in use. The quantity of product to be returned is entered on the pre-set device and pumping is started. When the product return is complete, the meter pre-set shuts off product flow and the hoseend nozzle is manually closed. The blowdown valve Bd is manually opened. This allows compressed air from the air tank AT to purge product from the bottom-loading pipework from Pt back into the compartment. Duration is approximately 2-5 seconds. The hose end nozzle is then removed from the product return spout, the product return guard bar lowered into its rest position which then deactivates the product return system. The system will then print the words product transfer on the delivery ticket. The software issue status of the EMR is displayed upon switch-on. Current issue status is C05 (without product return) or C06 (product return version) Security features and interlocks If during a normal delivery, the product return guard bar is raised, the delivery is terminated and a ticket is automatically produced detailing the volume of product delivered. 6 APPROVAL CONDITIONS The certificate is issued subject to the following conditions: 6.1 Legends and inscriptions The instrument bears the following legends: CE marking Supplementary metrology marking Notified body identification number Accuracy class Serial number Manufacturers mark or name Certificate number The viscosity or liquid types measured: 7 LOCATION OF SEALS AND VERIFICATION MARKS 7.1 Location of markings and securing (sealing) arrangements The following shall be sealed to prevent unauthorised adjustment or dismantling: (a) (b) The EMR3 electronic register shall be sealed as shown in Figure 10. The register shall be sealed as described in section An alternative sealing arrangement is shown in Figure 13. The plate referred to in Section 5 shall be sealed or welded to a support of the system.

Typical sealing arrangement is shown in Fig AUTHORISED ALTERNATIVES Having the following authorised alternatives 8.1 Having the system as described in the descriptive annex but without the Mechtronic product return system. 8.2 Having the special gas extractor electronic control cabinet manufactured so that the electronic control module is separate from the pneumatic control thus allowing maintenance work to be carried out on the pneumatic components without breaking the electronic module s seal. 8.3 Volume conversion A temperature correction algorithm is stored in the EMR³ for automatic volume correction when in the temperature correction mode. Volume conversion may be implemented using an optional temperature probe. A thermometer icon is displayed when being used in volume conversion mode Electronic Temperature Probe This is a two-wire thermistor which is used as an associated measuring instrument. It is manufactured by US Sensor Corporation and has part number USP2119. The temperature sensor (figure 12) is installed in the fuel delivery pipe within one metre from the flow meter; a typical installation is shown in Figure 16. Other temperature probes may be used in place of the above thermistor provided they meet the accuracy requirements of OIML R117 paragraph NOTE: PT100 type temperature probes will not operate with the EMR³ system Calibration of the temperature probe The temperature probe is calibrated at 0 C in the C&C mode with the probe immersed in a water/ice mixture. After calibration, this setting cannot be altered without breaking the seal on the Register Head. The following procedure shall be used: 1. Fill the bottom (about 100 mm) of a 1 litre container with ice. 2. Centre the temperature probe in the container, and then put ice all around it and on top of it until the container is full. 3. Fill the container with water until it is level with the ice. 4. Verification should be performed in still air and out of direct sunlight. 5. Allow 2-5 minutes for the temperature measuring devices to stabilize. 6. Select 0 C for the CALIBRATE TEMP on the EMR³ whilst in C&C mode. (Refer to EMR³ Set up and Operation Manual No: Revision: L for detailed information on using the setup menus.) To test a probe, connect each lead to an ohmmeter and measure the resistance. At 25 C, the meter should read about 10 K ohms.
10 An error code E08 will be displayed if the probe wires are either shorted together or are not connected to the TP terminals in the EMR³ Indication of measurement result A legend shall be affixed adjacent to the volume indication clearly indicating that the volume dispensed is corrected to 15 C. The receipt also indicates that the volume dispensed is corrected to 15 C (Figure 17) Securing The temperature sensor is secured to prevent removal from the fuel line. A sealing wire is threaded through a pre-drilled hole in the probe body and passed around the pipe, the wire ends are drawn taught and secured with an approved seal. The probe lead is hard wired within the EMR3 unit which is secured to prevent unauthorised entry. 8.4 Connection of OutTrak imeter, data monitoring device The OutTrak imeter box (Figure 14) may be connected between the electronic register and the printer. The OutTrak imeter System is designed to obtain transaction data generated by the electronic register and then passed onto an onboard computer for invoicing purposes. The legal data is not affected and passes through the imeter box to the printer and prints receipts as described in the certificate, the extra invoicing data is printed on the end of the legal receipt. Further invoice information generated by the on board computer can be printed on the onboard printer via Port 2. Note: This invoice information is not intended to replace the legal printed transaction data. There are three serial ports on the imeter box: - Port 0 is the input port from the meter, this requires the purple cable. - Port 1 is the output port from the box to the printer, use the white cable for this. - Port 2 is the control port, this can either be connected directly to the on-board computer or to a Bluetooth adapter. The software version loaded on to the imeter box can be checked by a switch located in a small opening on the side of the box. Turn ON switch 3 and power up the imeter, a message will then be sent to the printer with the version details. Once the information is printed, switch 3 is switched OFF and the imeter box can be reset ready for use. A message similar to the following will print on the meter printer: OutTrak Software Services Ltd. RS232 Multiplexer 3-Port Electronic Meter Interface Module Build Version Operating Mode: A The unit is sealed with tamper evident seals on two sides of the box and should be removed from the system if found to be damaged.
