Application:Measuring the volume of cold or hot potable water passing through the pipeline
FEATURE
◆Dry type, small, light, 8 digits, magnetic drive, magnet
◆resistance, 360 degrees free rotating register, corrosion
◆resistant body, inlet strainer, Low Head loss, easy and long term clear reading etc.
WORKING PRINCIPLE
◆Water passing through the water meter, causing the turbine to turn.
◆The turbine rotation is magnetically transmitted to the register on which the reading is made. Reeding is accomlished by means o pointersand numbered cylinders with high-resolution. Shock-resistant dal.
STANDARD

◆Hot Water Meter: ISO 4064 Class B
WORKING CONDITION:
◆Water temperature:≤40℃ for cold water meter
≤90℃ for hot water meter
◆Working pressure:≤1MPa or 1.6MPa optional(10bar or 16bar optional)
MAXIMUM PERMISSIBLE ERROR
