IC card water meter

Application:
IC card water meter is new generation of Intelligent water meter which applies the most advanced low power consuming IC, special electric control valve and the latest shell molding technology. It can work as a prepaid water meter and calculate the water rate automatically. It can also remind you of the state and avoid water pilfering. IC card water meter can be applied in both domestic and industrial use. It is the best assistant for the water states management.

Quality:
Completely plastic shell, fiberglass reinforced polymerization amine (UL NO.: E154352: SGS Report NO.: CE/2006/34019)
•Electric stainless steel switch, Low power consuming, low pressure loss, perfect hermetization. •Double dry reed switch pulse transmitting, Reliable data output, magnetic resistance.
•One meter, one code.
•Outer power supply, battery is also ok.
•Warn and shut down the switch when lacking water. Insert card to switch on.
•Warn and shut down the switch when the battery is out of service.
•Clock electro-circuit inside to switch on and shut down the switch regularly, preventing from valve blocked up.
•Support the ladder water price and southern seasonal water price.
•LCD screen, low power consuming.
•Identifiable remaining water quantity. MAXIMUM PERMISSIBLE ERROR Between Qs.flowrate and Qt flowrate Max. reading error ±2%. Between Qt flowrate ( Not including Qt): Max. reading error ±5%
