  NB-IOT Water Meter

water meter

  二、NB-IoT water meter indroduction

In order to meet the requirement of water suppliers intelligent management, we develop its own NB-IoT water meter,which can support remote meter reading,remote control and remote payment.It adoptes the dry-dial R160 water meter as measure basic meter.The dry-dial R160 water meter is in the leading domestic level ,which developed its own newly.NB-IoT water meter is linked by NB-IoT for network communication, realizes remote meter reading,remote control and remote payment automatically, effectively avoids the water suppliers' meter reading and charge work. It is convenient for the management department to control the water consumption of the water meter,and can save the manpower, material resources and financial capacity, and improve work efficiency.

  Features:

water meter Remote Meter Reading: report readings periodically ,regularly, actively.

water meter Remote Valve Control:remote shut off valve and open valve.

water meter Remote Payment:pay through internet,APP and WeChat, more easily and quickly.

water meter Prepay Function:Support for prepayment ,pre-storedwater and amount-overdraft.

water meter Warning Prompt: Low- battery warning,measure abnormal warning , prepayment and pre-storedwater over threshold warning and so on , setting different emergent water according to different users.

water meter Ladder Water Pricie: 5 kinds of ladder water pricie can meet different users' requirement ; bill calculation mode can be set as monthly, quarterly or yearly.

water meter Price adjustment in real time:adjust the price on the system when price adjustment without manual intervention. .

water meter Emergent Overdraft: NB-IoT water meter can start the emergency overdraft when communications bases

water meter has a malfunction or damage to ensure the water supply of users.

water meter Emergent Communication:NB-IoT water meter has emergency communication button,so management

water meter would be convenient for maintaining it, ensure the water supply of users even more.

water meter Abnormal Water Meter: water meter reports errors automatically when it detects abnormity,the system offers the solution according to the reporting error code,therefore,manager will be more easily.

water meter Long Battery Life:it with built-in 8500mAH lithium battery,ensure that it can be used for 6 year without changing.
