In order to expand the use of pressure instrumentation, direct mounting flange can be applied to measurement of strong corrosion, high temperature, high viscosity, easy crystallization, solidification and have solid easy media pressure, as well as the medium of certain measurements can not directly enter the general-purpose pressure gauge and easy cleaning to prevent sediment build-up pressure on occasions detect must apply by the isolator diaphragm and the pressure of general-purpose instrumentation systems divide to form a table. Flange table used mainly for oil, chemical, pharmaceutical, food, textile and other industrial sectors in the production process pressure Detect.
