APPLICATION
◆Measuring the volume of cold (hot) potable water passing through the pipeline.
FEATURE
◆Dry type, small, light, 8digits, magnetic drive, magnet
◆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 of pointersand numbered cylinders with high-resolution. Shock-resistant dial.
STANDARD
