FCLG Orifice Flow meter

 

Overview


FCLG orifice flowmeter is the high turndown ratio differential pressure flow device which combines the standard orifice plate with multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter and pressure transmitter).It can measure the flow of gas, vapor and liquid. It is widely used in petroleum, chemical industry, metallurgy, electricity, heating, water supply and other areas for process control and measurement.


Product Features


1.The structure of throttling device is easy to copy, simple, solid, stable and reliable performance, long life, low price.

2.The calculation of orifice is using international standards and processing. 

3.Wide ranges of applications, could measure all single-phase flow, some mixed phase flow can also be applied 

4.With standard throttling device, needs no real flow calibration, then it can be put into use.


Operating Principle


Placing a throttling element in the pipeline, when the fluid flows through the throttling element and occurs throttling, the difference of pressure (differential pressure) will be produced in front and rear both sides of the throttling element. When the fetch methods of fluid, working conditions, pipelines, throttle body, differential pressure are certain, the pipeline flow and differential pressure have a definite relationship. Therefore, the flow can be measured by the differential pressure.
