LUGB vortex flow meter is a kind of flow rate meters based on Karman Vortex theory, which is used to measure the volume flow or mass flow of gas, steam and liquid as well as the turbid liquid containing tiny particles or impurities. In addition, it can serve as the flow transducer in the automatic control system.

The ex-proof type of LUGB vortex flow sensor is verified according to the specification of GB3836-2000< ex-proof electrical equipment in explosive environment>. This unit, of which the Ex-marking is "ExiaIICT6" can be applied in explosion hazardous area Factory Class C, Group T6 or below.
