What is compensation function in vortex flow meter

28-06-2020

Vortex flow eter is an instrument used to measure the fluid flow of industrial pipeline, hich is widely used in many industries.

1.Saturated steam online density compensation

Vortex flow meter can achieve integrated temperature and pressure compensation, there is a strict one-to-one correspondence between the temperature and pressure of saturated stream.
The density of saturated steam can be a single function of its temperature or its pressure .according to the temperature value or pressure value of saturated steam ,the real ¨Ctime density value can be obtained through the table look-up method or formula calculation method.
In the flow measurement, the vortex flow meter can choose temperature compensation or pressure compensation flow eter. To select the flow meter with temperature compensation function. Turn on the flow meter temperature sensor to detect the measured steam temperature in real time to obtain the corresponding density value.

2.Superheated steam density compensation

Superheated steam is a kind of steam with special quality obtained by reheating saturated steam. Breaks the strick one-to-one correspondence between the inherent temperature and pressure of saturated steam. Vortex flow meter can treat superheated steam as a single medium during flow measurement. The density of superheated steam is a comprehensive function of its temperature and pressure.
When ordering vortex flow meter, choose temperature and pressure compensation type .in actual use ,the temperature and pressure sensor are simultaneously turned on to measure steam temperature and pressure value in real time ,and the density value can be accurately calculated according to the superheated steam density table or the density calculation formula.
