I. overview

Compound water meter, commonly known as mother-child meter, consists of large-caliber horizontal screw-wing detachable water meter, small-caliber rotor water meter and flow conversion valve. The meter has a large range ratio and is especially suitable for pipelines with large discontinuous flow and large flow variation. Large caliber water meter is driven by magnetic coupling. The machine core is removable and easy to maintain. Small caliber water meters with wet, liquid seal or dry type can be selected to meet the needs of various users.

Note: The counter of this series of water meters has another M-type glass fully sealed counter for users to choose.
