This range of water meter is used to measure the total quantity of cold potable water which consumed in household or a resident unit passing through the pipeline. As equipped with a built-in sensor, it can be used for a remote reading transmission system and converting the water consumption into electric output.
PRODUCT FEATURE:
lKeep all measuring data of common water meter, such as sustain its measuring accuracy and numeral display etc.
lAdopting unique design,advanced testing measures ensure a secure transmission and maximum distance between connected meter and a data collector is 150m
lTransmission Sensors with high exactly and resistance to interference enable a long term service
lApplicable to various kinds of data collector
lThe Sensors for option: Reed Switch / Hall Effect / Optical Switch
lThe pulse constant: 10 pulse/M3, 30 pulse/M3 or 100 pulse/M3

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 ±2% (Hot water meter±3% ).
WORKING CONDITION
Water temperature: 0℃≤t≤40℃(For cold water meter)
0℃≤t≤90℃(For hot water meter)
Water pressure: ≤1.0MPa
INSTALLATION REQUIREMENTS
1.The meter should be installed in horizontal position with the register face upwards
2.Pipeline must be flushed before installation
3.The meter should be constantly full of water during operation
SENSORS CONNECTING METHODS
