Non-Magnetic Valve-Controlled Smart Water Meter
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 (Q2≤Q≤Q4)
±5% in the low flow zone (Q1≤Q < Q2).
When water temperature exceeds 30℃, the maximum permissible error is:
±3% in the high flow zone (Q2≤Q≤Q4)
±5% in the low flow zone (Q1≤Q <Q2).
