Vortex street turbine flow meter

Vortex street turbine flow meter

Vortex flowmeter is according to the principle of Carmen (Karman vortex street research production of measuring gas volume flow of liquid, steam or, standard conditions or volume flow to mass flow volume flowmeter. Mainly used in industrial pipeline medium fluid flow measurement, such as gas, liquid, steam and other media.

Is characterized by low pressure loss, wide range, high precision, working condition of the measurement volume flow is almost not affected by the fluid density, the influence of the parameters such as pressure, temperature, viscosity. No moving mechanical parts, so high reliability, small amount of maintenance. Instrument parameters can be stable for a long time. Vortex street flowmeter using piezoelectric stress sensor, high reliability, can be in - 20 ℃ ~ + 250 ℃ temperature range. There are standard signal simulation and digital pulse signal output, easy to digital systems, such as computer systems.

What is a vortex flowmeter?

Eddy current flowmeter is a flow measuring device, which is most suitable for flow measurement when flow parts have problems. Vortex flowmeter works under the principle of vortex shedding. When the fluid flows through the blunt wall, oscillating vortices will be generated.

What is the purpose of a flowmeter?

Flow meter is used to measure the volume of a gas or liquid or the quality of the instrument. Flowmeter has many different names, such as flow meter, flow indicator, liquid flow meter, flow sensor, etc. However, they are flow rate measurement.

Product features

The detection element does not touch the medium under test, so the performance is stable and the reliability is high.

First no moving parts, simple and firm structure, long-term operation is reliable.

The measuring range is wide and the range ratio can reach 10:1.

The output signal or current signal is proportional to the actual flow of the current.

Small subloss (about 1/4-1/4 of orifice flowmeter), belongs to energy-saving products.
