Orifice Plate Flow Meter
orifice plate flowmeter
Detailed Description
Product Features
- The throttling device of the orifice flowmeter has a structure that is easy to replicate. It is simple, robust, with stable and reliable performance, and a long service life.
- Orifice metering adopts standardized design and processing.
- The orifice flowmeter has a wide range of applications. It can measure all single-phase flows and can also be used for some mixed-phase flows.
- Standard throttling devices can be put into use without actual flow calibration.
- The integrated orifice flowmeter is easier to install, requires no impulse lines, and can be directly connected to a differential pressure transmitter and a pressure transmitter.
Features of Smart Orifice Flowmeter
- Uses imported single-crystal silicon smart differential pressure sensor.
- Complete self-diagnostic function.
- The range of the smart orifice flowmeter can be programmed and adjusted.
