Throttling device orifice flowmeter structure easy to copy, simple, solid, stable performance, reliable, long duration, low prices. Rangers orifice and processing of international standards in mind, a wide range of orifice flowmeter cited application, all single-phase flow measure, part of the mixed phase can also be applied. Standard throttle rotor without real-calibration, you can put into use. A body orifice meter installation easier, no impulse control, can be directly connected to differential pressure transmitters and pressure transmitters. Inligent orifice flowmeter features: the use of imported crystal smart sensors, high precision and perfect self-diagnosis function. Orifice flow meter of its range can be smart self adjusting, inligent orifice flow meter can display the cumulative flow, instantaneous flow, pressure, temperature. With online. Dynamic full compensation, the smart orifice flowmeter also has a self-diagnosis, self-set range.
