Multivariable Vortex Flowmeter for nitrogen is a vortex air flowmeter.
The Multivariable Vortex Flowmeter operates as follows:
Under specific active conditions, a part of the kinetic energy of the fluid is transformed into fluid vibration, and its vibration frequency has a definite proportional relationship with the flow rate (flow ). Flowmeters based on this principle are called fluid vibration flowmeters.
At present, there are three types of fluid vibration flowmeters: vortex flowmeter, precession (vortex precession) flowmeter and jet flowmeter. Fluid vibration flowmeter has the following characteristics:
1) The output is pulse frequency, and its frequency is proportional to the actual volume flow of the measured fluid, which is not affected by fluid composition, density, pressure and temperature;
2) Wide measuring range, the general range can reach more than 10:1;
3) The accuracy is above average level;
4) No moving parts, high reli…
