Industrial vortex flow meter with 4 - 20 mA high accuracy
Quick Detail:
Description:
LUGB type flow meter is a kind of velocity flowmeter,based on Karman Vortex Street theory,adopt piezoelectric crystal to measure the vortex frequency produced by fluid flowing through the triangular prism in the pipeline,then the flow value can be measured .Vortex flowmeter is widely applied in industry like petroleum,chemical,light industry,power supply,heat supply,etc.
LUGB series Vortex flow meter is a type of international advanced flow meter designed on the basis of karman vortex street principle. Vortex flow meter is wildly used in petroleum,chemical industry, light industry, heating power and other industries. Vortex flow meter have the characteristics as below:
Its characteristics are no pressure loss, no moving parts and no
maintenance. Though it is similar to Electro Magnetic Flowmeter the
one advantage Vortex Meter has over EMF is the medium need not be
conductive as in the case of EMF. This flowmeter adopts
piezoelectric sensor, has high reliability, and works with in –200C
to +2500C. It gives standard analogue signal (4 ~ 20mA) or Digital
pulse signal outputs. It is compatible with digital systems like
Computer, DCS Systems, Dataloggers, etc.
If you have any question PLease contact us. SKYPE :susan86861 .
Applications:
Vortex Flow meters can be used for measuring the flow of steam, gas and liquid.

Competitive Advantage:
Our products have competitive price advantage.As flow passes a bluff body in the flow stream vortex meter, the
vortices create low and high pressure zones behind the bluff body,
or shedder bar. Our vortex flow meters are designed with a
piezoelectric crystal sensor to detect the pressure exerted by the
vortices on the velocity sensor.
