WATER METER > MULTIJET METERS
DEFINITION:
 

 

Set of moving device that fitted into a closed conduit driven directly by water flow. Its turbine rotor rotates about the axis which is perpendicular to water flow.
 
WORKING PRINCIPLES:
    Water flow drives vane rotate. Rotating times which is proportional to water flow speed are gathered, hence total volume passed through water meter is recorded.
