SIKA's gearwheel type VZVA positive displacement flow sensor records volume flows of liquids with both high and changing viscosities. The high-precision sensors work according to the displacement principle. The high resolution combined with reliable measurement accuracy makes the sensors especially useful for applications involving the measurement of small and minimal volumes. A very precisely adjusted gear pair within the casing forms the measuring element. The inflowing medium causes the gear pair to rotate. Contactless sensors scan the rotary motion. Since each tooth generates a pulse, this results in a very high resolution. Consequently, even the smallest volumes can be measured or dosed precisely. The measurement unit contains two pick-offs that are circumferentially offset by ¼ of a tooth pitch to generate a two-channel flow-proportional frequency signal. Suitable processing of the signal provides a higher resolution and the option to identify the flow direction. The maximum pressure drop should not exceed 16 bar. This limits the measurement range of high viscosity media (see pressure drop diagrams). The measurement accuracy increases with an increase in viscosity of the media.

The WIKA CPC8000-H Precision high-pressure controller is especially suited as a factory or working standard for the automatic testing or calibration of all types of high-pressure measuring instruments, due to its high accuracy and control stability. However, autofrettage applications or cyclic pressure-load tests are also ideal application areas, thanks to its robustness and reliability. For the supply to the controller, other than the voltage supply, only clean dry compressed air for the pneumatic control circuit is needed. As a pressure medium on the output side, hydraulic oil or water (or other media on request) can be used. The CPC8000-H consists of two components, the WIKA CPC8000-HC pressure controller and the WIKA CPC8000-HM hydraulic module with the reference pressure sensors. The hydraulic module is available in two versions, as a low-pressure version with a pressure range of 5 … 700 bar (75 … 10,000 psi) bar and a high-pressure version with a pressure range of 20 … 1,600 bar (290 … 23,000 psi) with each suitable reference pressure sensors. The complete system is available as a 19″ plug-in case or built into a 19″ rack. The sensors can be changed via the front of the hydraulic module, without having to dismantle the complete controller. Through its specialist technology, the desired pressure value from the controller is regulated quickly and simply. Maximum ease-of-use is achieved through a large touchscreen and simple and intuitive menu navigation. In addition, its easy operability is further supported by the availability of a large number of menu languages. On the large touchscreen, all necessary information such as current measured value and set point can be found on a single screen. Optionally, the measured values can be displayed in other pressure units additionally. The pressure controller can be remotely controlled via serial interfaces available. Through these, a wide range of emulation command sets for other pressure controllers are available.
