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 CPC7000 pneumatic high-pressure controller always provides a suitable calibration solution on account of its accuracy class. Its outstanding control performance is particularly impressive thanks to special valve technology and the high-accuracy pressure sensor as a measuring unit. With this the WIKA CPC7000 pneumatic high-pressure controller is suitable as a factory or working standard for the testing or calibration of any type of pressure measuring instrument. The WIKA CPC7000 pneumatic high-pressure controller is available as a desktop instrument or as a 19″ rack-mounting kit. The sensors can be changed via the front, without having to take out the complete controller, e.g. out of a calibration rig (plug-and-play). The touchscreen, through its intuitive user interface, delivers ease of use. A large number of menu languages adds to its user-friendliness. In addition to specifying a specific pressure set point, either by entering it via touchscreen or sending it via a remote interface, the pressure can be changed in defined, programmable steps by using the STEP buttons. Moreover, the user can also easily create extensive test programs using the instrument menu. Depending on the application, the control rate can be set as a user-defined variable rate. The WIKA-Cal calibration software enables the convenient calibration of pressure measuring instruments and the generation of test certificates. Additionally, the instrument can also be remotely controlled using the serial command formats, the Mensor standard, SCPI or further optional command sets are available. There is an IEEE-488.2, RS-232, USB and an Ethernet interface for communication with other instruments, and thus the instrument can be integrated into existing systems.
