Smart Cooling/Hot Water Meter- ZSL

1 Smart Cooling/Hot Water Meter- ZSL

         DN15~DN25             DN32~DN40                 DN50~DN300

Application                                                                       

Use for measure flow of Cooling or hot water in pipelines. it’s a prepay 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).

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 manger 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 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；
