technical field

Background technique

Vortex flowmeter is a volume flowmeter that measures the volume flow of gas, steam or liquid, the volume flow of standard conditions or mass flow according to the Karman vortex principle. It is mainly used for the flow measurement of medium fluids in industrial pipelines. Such as gas, liquid, steam and other media, which are characterized by small pressure loss, large measuring range and high precision, and are almost not affected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring the volume flow of the working condition. Dynamic mechanical parts, so the reliability is high, the maintenance is small, and the instrument parameters can be stable for a long time. The vortex flowmeter adopts piezoelectric stress sensor, which has high reliability. There are analog standard signals and digital pulse signal output, which is easy to be used with digital systems such as computers. It is a relatively advanced and ideal measuring instrument.

At present, most vortex flowmeters on the market are avoided to be used in pipelines with large vibration. Since the vortex flowmeter itself is relatively easy to be affected by vibration, if it is installed on a vibrating pipeline, additional installation is required. The device for fixing the front and rear pipes, and after the fixing is completed, the vibration is still transmitted to the vortex flowmeter through the rigid connection device because the fixed method is still used for shock absorption, which not only wastes the installation time, but also has the effect of shock absorption. It's not very obvious either.
