NB-IOT 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:
Remote Meter Reading: report readings periodically ,regularly, actively.
Remote Valve Control:remote shut off valve and open valve.
Remote Payment:pay through internet,APP and WeChat, more easily and quickly.
Prepay Function:Support for prepayment ,pre-storedwater and amount-overdraft.
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.
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.
Price adjustment in real time:adjust the price on the system when price adjustment without manual intervention. .
Emergent Overdraft: NB-IoT water meter can start the emergency overdraft when communications bases
has a malfunction or damage to ensure the water supply of users.
Emergent Communication:NB-IoT water meter has emergency communication button,so management
would be convenient for maintaining it, ensure the water supply of users even more.
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.
Long Battery Life:it with built-in 8500mAH lithium battery,ensure that it can be used for 6 year without changing.
