Description
FEATURE
â—†Dry type, small, light, 8 digits, magnetic drive, magnet
â—†resistance, **0 degrees free rotating register, corrosion
â—†resistant body, inlet strainer, Low Head loss, easy and long
term clear reading etc.
WORKING PRINCIPLE
â—†Water passing through the water meter, causing the turbine to
turn.
â—†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.

â—†Hot Water Meter: ISO ***4 Class B
WORKING CONDITION:
â—†Water temperature:≤*0℃ for cold water meter
≤*0℃ for hot water meter
â—†Working pressure:≤1MPa or 1.6MPa optional(*0bar or *6bar
optional)
MAXIMUM PERMISSIBLE ERROR
â—†In the lower zone from Qmin inclusive up to but excluding Qt is:
Cold potable and Hot water meter ±5%
â—†In the upper zone from Qt inclusive up to and including Qs is:
Cold potable water meter ±2%, Hot water meter ±3%.
NOTE
1.Technical data conform to International Standard ISO***4
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
