EMCO Cone Meter, type M-CONE

Principle: The differential pressure is measured with a differential pressure transmitter between the up-stream tapping in the wall of the cone meter and the down stream tapping in the cone.




The most common has the up stream pressure taken from a tapping in the wall of the cone meter and the down stream pressure taken from the down stream side of the cone and lead to a tapping in the wall
