Orifice plate flowmeter is a high range ratio differential pressure flow device composed of a standard orifice plate and a multi parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter, and pressure transmitter). It can measure the flow of gas, steam, liquid, and lead, and is widely used in process control and measurement in the fields of petroleum, chemical, metallurgy, power, heating, water supply, etc. The throttling device, also known as the differential pressure flowmeter, consists of a primary detection element (throttling element) and a secondary device (differential pressure transmitter and flow display instrument), which are widely used in gas applications. Flow measurement of steam and liquid. It has a simple structure, easy maintenance, and stable performance.

1. The standard throttling element is fully used and recognized by the International Organization for Standardization. It can be put into use without the need for real flow calibration and is the only one in flow sensors;
2. The structure is easy to replicate, simple, sturdy, stable and reliable in performance, and inexpensive;
3. Widely applicable, including all single-phase fluids (liquid, gas, steam) and some mixed phase flows. The diameter and working state (temperature, pressure) of the general production process can be measured;
4. The detection components and differential pressure display instruments can be produced separately by different manufacturers, facilitating specialized scale production.
