Integrative Orifice Plate Flowmeter

2021-04-07 16:29:55 100

● OVERVIEW

The integrative orifice plate flowmeter produced in our company is designed to assemble the orifice plate pressure device and integrative flowmeter at the factory, minimize the measure error caused by assembling or mismatching with the second instrument, maximize improvement of measurement accuracy of orifice plate pressure device. At the same time, to meet the requirements of customers, the installation and maintenance costs will be at least. Integrative flowmeter integrates differential pressure and pressure transmitter, support input of PT100 temperature sensor.
