Wireless remote reading water meter(Mechanical & electrical separation type)
Adopting wireless radio frequency technology, integrated micro-power multi channel embedded wireless module, the realization of the various parts of the wireless data transmission. The water can be used to realize remote measurement and storage, copy control, and can automatically detect the battery status, operation status and other information, support the price ladder. No difficulty in construction, also it has the advantages of cost saving, simple operation and convenient maintenance.
Wireless remote reading LoRaWan water meter with brass valve control,over 6 years battery life
We can customize to your requests, with or without gateway,both we can support.
Product Features:
1) Low power LoraWan wireless communication technology, long transmission distance, strong penetration.
2) Wireless module and base meter with split structure, plug & use, on site renovation & maintenance easily.
3) The water meter adopts dual protection and maintenance of integral structure seal and gummed seal, which can completely reach the IP68 waterproofing grade and solve the problem of waterproof and moisture-proof thoroughly.
4) Using wireless single wake-up single copy mechanism, more energy saving and power saving.
5) Adopts wireless wake-up single-reading mechanism, power saving.
6) When the remote water meter has low voltage battery and sensor failure, it can upload the fault alarm to the meter reading platform.
7) The wireless remote transmission valve control water meter adopts the wet rotor copper shell base meter, and the wireless remote transmission non-valve control water meter uses the high sensitive wet rotor nodular iron shell base meter, the start flow rate ≤2L/H.
8) Wireless remote valve control remote water meter, remote switch valve;
9) Wireless concentrator can load 1000 water meters and support remote upgrade function;
10) Support multistage relay, special repeater built in large capacity lithium battery, the meter can also be set as relay, used in the field wireless communication dead-angle reading.
