General Situation
The orifice plate throttling device (orifice flowmeter) is a new generation of instruments that integrates flow, temperature, and pressure detection functions, and can perform automatic temperature and pressure compensation
The orifice flowmeter adopts advanced microcomputer technology and micro-power consumption technology, featuring powerful functions, compact structure, simple operation, and convenient use.

Feature
• The orifice plate calculation adopts international standards and processing.
• The standard throttle device can be put into use without real-flow calibration. • The integrated orifice plate is easier to install, without the need for a pressure conduit, and can be directly connected to a differential pressure transmitter and a pressure transmitter.
• Wide range of applications, capable of measuring all single-phase flows and also applicable to some mixed-phase flows.
• The throttle device is easy to replicate, simple, sturdy, stable and reliable in performance, has a long service life, and is affordable
