Overview This specification applies to Cold-water meters based on a direct mechanical
Process
Involving the action of the velocity of water through its effect on the rotation
Rate of a
Moving part of a meter (Propeller meter), or through the use of volumetric
Chambers
With mobile piston (piston meter) for meter size 15mm (1/2'') and 20mm
(3/4'').
It applies to water meters with nominal flow rate up to 4, 000m3/h and with a
Maximum working pressure of 16-bar.
For this purpose, water should be considered cold when its temperature is in the
Range
Of 00C to 400C.
Stability and Leak proof Water meter must withstand a pressure value of up to 1.6 times of its MAP
Value and
There should be no leakages
