NB-IoT Non-magnetic valve control smart water meter，Adopting advanced anti-strong magnetic measurement technology and NB-IoT communication technology, it can remotely control the valve switch. The non-magnetic sensor measurement is based on the principle of metal detection. The sensor detects the rotor with metal flakes and converts it into a pulse measurement signal, which is not interfered by external strong magnets and can measure accurately.

The water meter is equipped with Bluetooth function, and the administrator can use a mobile phone or a handheld device to calibrate the water meter, set data reporting frequency, valve control and other related functions. The whole machine uses industrial-grade ultra-low power consumption chips for real-time data processing, which has many advantages such as low power consumption, long service life, long wireless communication distance, and simple installation and maintenance.

Features:

l1. Accurate measurement: non-magnetic sensor pulse sampling measurement method, the minimum sampling accuracy can be as accurate as 1L;

l2. Long service life: The whole machine adopts ultra-low power consumption power management technology and is equipped with a large-capacity battery, so the whole meter has a long service life;

l3. Controllable valve: the valve can be configured according to customer needs, and the data cloud platform can remotely control the valve switch;

l 4.Magnetic wake-up: The user can wake up the water meter by absorbing the position of the magnetic switch with a magnet. After the water meter wakes up, it is convenient to set the relevant parameters of the water meter and report the data;

l5. Simple parameter setting: adopt low-power bluetooth communication technology, and the parameters of the water meter can be set without dismantling the meter;

l 6.Adjustable data reporting cycle: the handheld can set the water meter reporting cycle, the default is 24 hours/time;

l 7. Data supplementary copying: under complex electromagnetic conditions, the water meter data can be read by mobile phone APP;

l 8. Flexible charging mode: flexibly configure the water meter charging mode according to customer needs, and support pre-paid or post-paid charging modes;

l 9.Battery voltage detection: battery voltage self-monitoring, detection data can be reported to the cloud platform;

l 10.Signal strength detection: NB-IoT signal strength self-detection, the detection data can be reported to the cloud platform;

l 11. Automatic time calibration: During the data reporting process, the time calibration can be completed independently to ensure accurate timing;

l 12.Simple maintenance: the battery compartment is easy to open, the battery can be replaced, and maintenance is convenient.
