Gear Type Flow Meter VC KRACHT • 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 Vgz. • The signal...

Gear Type Flow Meter VC KRACHT • Optimized for individual applications because the series have been rendered media-specific by means of differing clearances, bearing variants and materials. • Wide measuring ranges with sizes graduated to meet specific requirements. • Measurement independent of viscosity within the specified ranges. • Low pressure drop • High-response measurement • High working pressure • Low noise emission • High-precision measurement with outstanding reproducibility • Temperature-independent output signals over a wide temperature range • High degree of accuracy, even with low...

Gear Type Flow Meter VC KRACHT • The accuracy figures quoted by KRACHT refer to the geometric tooth volume Vgz, that is to say the percentage deviation applies to the current value in each case. • The linearity error over the entire measuring range is < ± 0.1 % • Reproducibility of a measured value is < 0.1 % • 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. • The accuracy values quoted by Kracht are confirmed by the DKD...

Gear Type Flow Meter VC Explosion-Proof 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 K 130 (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 K 130 is carried out in the safe area. • Volume counter and switching amplifier are electrically connected...
