 What are the advantages of orifice flowmeter
 

The main component of the orifice plate flowmeter is the advanced orifice plate valve (using the advanced valve type orifice plate throttling device), which is mainly used for the generation and transmission of the signal of the differential pressure flowmeter, which can realize the online replacement of the orifice plate without affecting the conveying medium , no additional pipeline; there is an orifice plate installation and positioning mechanism in the device, and the calibration accuracy level is 0.5; the device is equipped with upper and lower two sealing chambers, as well as slide valve components, without additional pipelines.

The seal between the upper and lower chambers of the device adopts a fully hard sealing structure, the valve plate and valve seat are made of 22Cr surfacing hard alloy, and there is an auxiliary structure for injecting sealing grease, which can prevent the precipitation of dirt on the sealing surface of the valve seat and valve plate. ; Use flange pressure standard orifice plate as flow detection element. Orifice flow measurement system generally consists of throttling device (standard orifice), differential pressure transmitter and data processor (square root calculator or computer).

Orifice flowmeter.jpgOrifice flowmeter is a high range ratio differential pressure flow composed of standard orifice and 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 industry, metallurgy, electric power, heating and water supply, etc.

The throttling device, also known as the differential pressure flowmeter, is composed of a primary detection part (throttling part) and a secondary device (differential pressure transmitter and flow indicator), which is widely used in the flow measurement of gas, steam and liquid. It has simple structure, convenient maintenance and stable performance.
