990.15 Flanged Process Connection Diaphragm Seal

990.15 Flanged Process Connection Diaphragm Seal

2282

Together with a block flange or a saddle flange, the WIKA 990.15 diaphragm seal forms a perfectly matched system. Through the process connection via block flanges or saddle flanges, compact assemblies can be optimally realised at the measuring point. Depending on customer requirements, the model 990.15 can be subsequently integrated into a process using the accessory models 910.19, 910.20 and 910.23. The process connection is designed as a flange connection. The measuring instrument is in a vertical position. Applications Specifically for connection with block flange or saddle flange and to combine with bourdon tube pressure gauges Suitable for corrosive, contaminated, hot or viscous pressure media Chemical and petrochemical industry

VZVA Positive Displacement Flow Sensor

VZVA Positive Displacement Flow Sensor

7830

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.
