2 I. Application The Vortex Flow Sensors are combined flow- and temperature transmitters with the intended use in a domestic hot water circuit. The sensor is intended to be used on the secondary heat exchanger side. The flowsensors are now available in a series ranging from litre/minute and 2-40, and The measurement of temperature is always C. The flow signal is to be used for Control of three-way valve Control of burner (required power estimated from DHW flow rate) The integrated temperature signal is to be used for Control of burner (burner power regulated according to actual DHW temperature) Elimination of solitude temperature sensor All Grundfos Direct Sensors are coated with a proprietary and extremely durable coating enabling accurate, cost-effective and robust piezo-resistive sensors. More in section II and IV. The benefits in a boiler derived from using a pressure sensor in conjunction with a flow sensor is described in the Application Note for Pressure Measurement. 2 of 17

4 Temperature (DHW) Setpoint Flow sensor alone Temperature sensor alone Combined flow and temperature sensor Time With a stand-alone temperature sensor a slow and fluctuating regulation of the DHW temperature is obtained. The boiler is able to compensate for changes in inlet DCW temperature, and changes in the efficiency of the heat exchanger, but not with the consumption/flow of water. With a stand-alone flow sensor a fast regulation is obtained, but the temperature of the water is usually lower than required to reduce the risk of scoldering. By combining the two - the best of both worlds will occur: A fast and accurate regulation of the DHW temperature. The Grundfos combined flow and temperature sensor is designed and validated for use on the hot side of the secondary heat exchanger. 4 of 17

6 Outputs Influence of supply voltage on output signals In relation to the diagram on connections on the following page, please note the following. The sensor is designed to deliver ratiometric signals. This means, that the output signal will change in proportion with the supply voltage for constant temperature or flow, as seen from the above diagrams. An onboard microprocessor is calibrated individually for each sensor to deliver a linearized signal of the flow and temperature. Ratiometric output enables a higher accuracy and lower system cost in applications, where the sensor is connected to an A/D converter using the supply voltage as reference voltage. The diagram on the following page illustrates the recommended connection of the sensor to a boiler control. To avoid unintended intrusion of water, it is recommended to mount the sensor upside down. 6 of 17

10 III. Functionality Theory of operation The Vortex Flow Sensors are integrated flow and temperature measurement systems designed and validated for harsh aqueous environments. The system elements are a flow pipe with an integrated bluff body and a differential pressure sensor. The flow measurement is based on the Vortex principle. When a bluff body is placed in a flow inside a pipe, a series of vortices will be generated periodically on each side of the bluff body. These vortices propagate down steam giving rise to periodic pressure variations, which can be detected by the differential pressure sensor. The frequency of the pressure variations is proportional to the volume flow through the pipe. Operating principle The bluff body is designed to optimize to pulse strength of the pressure variations at the position of the differential pressure sensor. The bluff body is an integrated part of the injection molded flow tube, whereas the miniature differential pressure sensor is mounted through a slit in the tube, ie. flow ranges is set by the tube diameter, which is easy to modify. The differential pressure sensor key elements are a silicon bulk micro machined chip and a microprocessor-based signal-conditioning circuit, both on the same PCB. The conditioning circuit converts the pressure reading to a signal proportional to the volume flow through the pipe. The electronics are protected in an IP class 44 composite housing. In water the minimum detection of flow is 1.3 litre/minute in a 10mm pipe. For other pipe diameters please refer to the table on page of 17
11 The uniqueness of the chip is that the pressure and temperature sensitive area (the membrane region) is coated on both sides by an extremely corrosion and diffusion resistant thin film. The coating provides direct environmental robustness of the chip. This is the key technology making the high level of integration and miniaturization of the flow sensor possible. The chip has a square membrane, which deflects due to pressure. Strain gauges are incorporated in a Wheatstone bridge configuration on stress intensive positions on the membrane. The temperature coefficient of the bridge resistance is used as temperature sensor. The separation of the media and media-free zones is provided by an O-ring sealing. The sealing is centered around the membrane, and symmetrically on both sides of the chip, to ensure minimum stress coupling from the packaging. The sensor chip and the electronic components are mounted on a PCB using a combined chip on board and a lead free SMD technique. The exterior composite housing defines the pressure inlet sealing geometry. It is furthermore the carrier and environmental protection of the PCB. The media exposed part of the housing is one piece with one O-ring sealing to the atmosphere. Pressure port (one on pressure sensor, two on flow sensor) O-ring that seals water from electronics Sensor housing Guiding element for o-ring Electrical contacts to PCB Printed circuit board (PCB) Sensor chip (membrane detects pressure and temperature) Protective coating (resistant to corrosive media at high temperatures) Cross section of sensor chip and sealing configuration. 11 of 17
12 Signal Conditioning The non-compensated signals from the pressure and temperature detection circuits are feed into a microprocessor and converted to the digital regime after amplification. The microprocessor conducts algorithms to overcome pressure offset prior to and frequency detection of the pressure pulses. The frequency is converted to a flow based on calibration data, which are dependent on the geometry of the flow tube. The calibration data is programmed in the production line via a digital bus. The bus (optionally connected to the external pins) also communicates the calibrated sensor signals and provides control to system check procedures. On the pins the calibrated signals are reconverted to analog, ratiometric V signals. Sensor chip Micro Calibration & temp. comp.

17 Attachment B: - Operation of flowsensor with various contents of glykole. Minimum flow Minimum Flow as function of glykole contents and media temperature 20 C 60 C % Glykole in water The accuracy of the flowsignal is unaffected by the viscosity of the fluid. However, the minimum flow that can be measured using the vortex flow principle changes with the viscosity and temperature of the fluid. As long as the amount of glykole is 30% or less, and the temperature of the liquid is 60 C or higher, the sensor is at a minimum flow of 3,3 litre/minute. At these conditions, the pressure drop over the sensor is 0.15 bar at 10 l/min. 17 of 17
