Non-Magnetic Valve-Controlled Smart Water Meter

M26 Non-Magnetic Valve-Controlled Smart Water Meter

▲The electronic unit is housed in an independent fully-sealed cavity, achieving an IP68 waterproof rating.
▲Valve Control: Features remote valve operation capability, enabling real-time manual valve switching or automatic remote valve operation integrated with both prepaid and postpaid utility payment systems.
▲The water meter can be configured via the NB-IoT platform network to transmit periodic reports at hourly, daily, and monthly intervals based on actual user consumption. Transmitted data includes cumulative water consumption, remaining battery capacity, and meter status.
▲The module maintains an Ultra-Low Power State during normal operation; magnetic triggering or button activation enables a single upload of real-time data and operational status.
▲The design fulfills comprehensive electromagnetic compatibility requirements including EMC, ESD, and EMI compliance for electronic products.

Details

Function Parameters Dimensions

This product is SECK Non-magnetic Valve-controlled Smart Water Meter. The non-magnetic valve-controlled integrated volumetric wireless water meter is a low-power wireless remote water meter based on NB-IoT narrowband cellular technology. It adopts a split design, does not change the traditional water meter structure, and does not affect the measurement accuracy and sensitivity of the water meter. It is an electronic remote water meter with integrated electromechanical components in an automatic meter reading system. The meter features micro-power consumption design and has characteristics such as high measurement accuracy, low starting flow, convenient meter reading, attractive appearance, high sensitivity, strong anti-interference capability, and long transmission distance.

 

The non-magnetic valve-controlled integrated volumetric wireless water meter, in conjunction with intelligent meter reading system software, completes the intelligent meter reading of water meter data in residential areas and achieves data sharing with the settlement center.

Note:

Indication error:

Within the water temperature range of 0.1 to 30, the maximum permissible error of the water meter is:

±2% in the high flow zone (Q2QQ4)

±5% in the low flow zone (Q1Q < Q2).

When water temperature exceeds 30, the maximum permissible error is:

±3% in the high flow zone (Q2QQ4)

±5% in the low flow zone (Q1Q <Q2).
