The flow meter for hydraulic testing is based on the differential pressure generated by the fluid sensing member installed in the pipe, the known fluid conditions and the geometry of the test piece and the pipe geometry.
The flow meter for hydraulic testing is based on the differential pressure generated by the fluid sensing member installed in the pipe, the known fluid conditions and the geometry of the test piece and the pipe geometry. It consists of a single test piece (throttle) and a secondary unit (differential pressure transmitter and flow indicator) for flow measurement of gases, vapors and liquids. It is widely used in small flow measurement and process control in petroleum, chemical, chemical fiber, steel, food, light industry, pharmaceutical and other industries.
