Gas turbine flowmeter

Gas turbine flow meters are mainly used for measuring the flow rate of medium fluids such as air, nitrogen, oxygen, hydrogen, biogas, natural gas, steam, etc. in industrial pipelines. When measuring the volumetric flow rate under working conditions, they are almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can remain stable for a long time. The gas vortex flowmeter adopts a piezoelectric stress sensor, which has high reliability and can operate within the working temperature range of -20 ℃ to+250 ℃. It has both analog standard signals and digital pulse signal outputs, making it easy to use in conjunction with digital systems such as computers. It is a relatively efficient and ideal flow meter.

The pulse frequency signal output by gas vortex flowmeter is not affected by fluid properties and composition changes, that is, the instrument coefficient is only related to the shape and size of the vortex generator and pipeline within a certain Reynolds number range. However, as a flowmeter in material balance and energy measurement, it is necessary to detect mass flow rate. At this time, the output signal of the flowmeter should simultaneously monitor volume flow rate and fluid density. Fluid properties and components still have a direct impact on flow measurement. The gas vortex flowmeter is a new type of flowmeter that measures fluid flow in closed pipelines based on the Karman vortex principle. Due to its excellent medium adaptability, it can directly measure the volumetric flow rate of steam, air, gas, water, and liquid without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure standard volumetric flow rate and mass flow rate, making it an ideal alternative to throttling flow meters.
