Tianjin U-ideal Vortex flowmeter is mainly used to measure the flow of the medium in industrial pipeline, Such as gas, liquid, steam and other mediums. It is characterized by low pressure loss, wide measuring range, high precision. The density, pressure, temperature, viscosity and other fluid parameters have no impact on measuring of the vortex flowmeter.

The Vortex flowmeter has no moving mechanical parts, with high reliability, small maintenance and simple & strong structure, Long time work is very reliable;
Simple installation, convenient maintenance;
Vortex flowmeter has the advantages of other flowmeter can not have both, widely used in petroleum, chemical, metallurgy, thermal power, textile, papermaking and other industries on the superheated steam, saturated steam, compressed air and gas (oxygen, nitrogen and hydrogen, natural gas, coal gas, water) and the liquid (such as: water, gasoline, alcohol, benzene) measurement and control.

Working principle:
Vortices occur alternately and regularly to the right and left under a given condition downstream of an object (delta shape bluff body) placed in the flow. This vortex is called Karman vortex, enabling you to know the flowrate from the frequency created. A vortex flowmeter is applicable to liquid, gas, and steam. It has no moving parts and features low pressure loss. It is an easy-to-use flowmeter with high durability and repeatability and is widely adopted in various fields including calorie transactions and calorie control.

Product Feature
Virtually No Pressure Loss
