Description
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 ◆Cold Water Meter: ISO 4064 Class A ISO 4064 Class B ◆Hot Water Meter: ISO 4064 Class B WORKING CONDITION: ◆Water temperature:≤40℃ for cold water meter ≤90℃ for hot water meter MAXIMUM PERMISSIBLE ERROR ◆ In the lower zone from Qmin inclusive up to but excluding Qt is ±5% ◆ In the upper zone from Qt inclusive up to and including Qs is: cold water meter ±2%, hot water meter ±3%. NOTE 1.Technical data conform to International Standard ISO4064 2.Both Class B and Class A is available. But Class B is popularly used. 3.Horizontally installation can reach accuracy of Class B.But if vertically installation reachs class A only. ACCESSORIES one meter with 2 pcs tubes,2 pcs nuts and 2 pcs gastkets for coupling.
