Orifice flowmeter is a high range down ratio throttling device composed of orifice plate throttling element and multi parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter, and pressure transmitter), which can measure gases, vapors, liquids, and is widely used in process control and measurement in Petroleum, Chemical, Metallurgical, Power, Heating, Water Supply and other fields.

The throttling device has a simple and sturdy structure, stable and reliable performance, and a long service life;

Widely applicable, all single-phase flows can be measured, and some mixed phase flows can also be applied;

The standard throttling device does not require real flow calibration;

The installation of integrated orifice plates is simpler, without the need for pressure-leading pipes, and can be directly connected to differential pressure transmitters and pressure transmitters;

Adopting high-performance intelligent differential pressure transmitters;

High accuracy, comprehensive self diagnostic function and intelligent differential pressure transmitter;

Can display cumulative flow rate, instantaneous flow rate, pressure, and temperature simultaneously;

In addition to online and dynamic full compensation functions, it also has self diagnosis and self setting range.
