Features

Low-Power Design with Waterproof Structure

It adopts an ultra-low power pulse sampling method combined with a low-power NB-IoT transmission module. The external split design places the electronic unit in an independent fully sealed cavity with IP68 waterproof performance, while maintaining the structure and accuracy of traditional wet-type water meters.

Convenient construction and installation, no wiring required
Suitable for situations with dispersed meter installations
Communication is mainly affected by the signal of the operator's base station
Meter reading data is actively reported, and control commands are issued remotely
The number of reports and time can be freely set
With Valve water meters can achieve prepayment when combined with the upper system
Supports emergency valve opening function in emergency situations
