  • Model :

Application
Use for measure flow of Cooling or hot water in pipelines. it’s a prepaid water meter, and have varies ways to warn the
customers to buy water on time, ZSL is accurate measurement and stable performance, especially apply for metering and
control of urban resident water. This water meter can be Plug-in Card (Contact Type) or Radio Frequency Card
(Non-Contact Type,GPRS type).


Plug-in card using for Urban Residential Areas or Water company, RF card using for difficult conditions, such as
outdoor, supermarket or pipe shaft.

Main Function
Prepay Function:  the users can get recharged in the management department ,when using the card the water meter will
read the amount of it, and the number will reduce according to water consumption, as it reduce to a certain number the
valve will closed automatic;


Card bounding: as first time using, the card will bounding to the water meter, and only the bounding card can be read
for recharging. others will not be recognized;


Prevent hoarding: the manager can set up the limited value for purchase by one time, and how much water the water
meters can stored, if the amount of card over the limited of the water meters, the water meter will not be recharged
successful, until the a certain amount of water be used up;


Reissue lost card: if the card lost, the user can reissue it the water in the lost card will not be lost;


Over run: if the water over run by a faulty valve, the water meter will record it and deduct them while next
recharging;


Prevent rust: the water meters will open-close in a certain time automatic, prevent rust or incrust;


No magnetic influence: if the meters detected long-term magnetic influence, the valve of will shut down
automatically in order not to wrong metering by magnetic influence;


Power Fail Safeguard: anytime the power failed, the operational data will be keep in memory for 10 years;


Low-battery warning: when the battery is in low voltage, the valve will shut down for warning, until the battery
change;
