EMCO Meter Run with Transmitter Flanges for
Compact Mounting, Type CompaQ


Principle: EMCO Meter Run type CompaQ is used as primary element in flow measurement of liquid, gas and steam according to the differential pressure principle. The differential pressure transmitter and 3 way manifold valve is mounted directly on the CompaQ ensuring an faster and more safe installation on site
