Construction and Function 3 4 5 6 2 1 7 Construction 1 Housing 2 Cover 3 Gear 4 reamplifier 5 Connector 6 Sensor 7 Bearing assembly Function The measuring gears are driven by the liquid flow on the principle of a gear motor. The gears run without contact in the measuring chamber. The bearing elements are low-friction ball or plain bearings. The movement of the gears is sampled without contact by means of two sensors located in the cover. Between sensor compartment and measuring chamber is located a pressure-resistant, non-magnetic separator plate. When the measuring mechanism rotates by one tooth pitch, the sensor emits a signal which corresponds to the geometrical tooth volume V gz. The signal is converted into a square-wave signal by the preamplifier. The two-channel sampling permits better resolution as well as recognition of the flow direction.

Accuracy Characteristics The accuracy figures quoted by RACHT refer to the geometric tooth volume V gz, that is to say the percentage deviation applies to the current value in each case. The linearity error over the entire measuring range is < ±.1 % Reproducibility of a measured value is <.1 % Accuracy checking forms part of quality inspection in every case. On request the result of the test will be documented in the form of an accuracy characteristic curve; an example relating to a series 1 VC 1 is given below.

Explosion-roof Design (ATEX) Function All volume counters are available in explosion-proof design according to ATEX. The explosion-proof design consists of the volume counter (intrinsically safe electrical apparatus) and the switching amplifier 13 (associated electrical apparatus). The type of protection intrinsic safety applies to this construction. The volume counter is installed in the potentially explosive atmosphere. The mounting of the amplifier 13 is carried out in the safe area. Volume counter and switching amplifier are electrically connected to each other. The switching am plifier evaluates the sensor signals and converts them to square-wave signals. Without switching amplifier, the volume counter must not be operated in the potentially explosive atmosphere. Cable lengths of up to 4 m / 1312 ft are possible between volume counter and switching amplifier. ED s for monitoring line breaks / short circuits, channel switching state and power supply are located on the switching amplifier.
