Details 
 Gas flow meter manufactured using Karman vortex street principle, has high accuracy, wide range, low power consumption, easy installation, simple operation, pressure loss, etc., measure the volume flow conditions or standard volume flow (integrated smart temperature, pressure compensation), according to user needs, with pulse or 4 ~ 20mADC current output. Natural gas is the ideal measuring instrument.
