Product details

Product description

This series of products is an electromechanical separated IoT water meter, which can separate the electronic device (data sampling, wireless transmission) and the mechanical water meter completely independently, and realize the wireless upload of water volume information through the NB-loT/Lora network.


Performance characteristics

Multi-flow rotor type: adopts domestic mainstream metering structure.

Liquid-sealed movement: high sensitivity; special liquid encapsulation of the character wheel window can keep the reading permanently clear.

Dry core: central magnetic drive, anti-magnetic interference, good stability, strong anti-freezing ability, and permanent clear reading.

Electromechanical separation: independent sealed structure: good interchangeability, easy maintenance, waterproof, moisture-proof, protection grade IP68.

Independently sealed battery: independent cavity, replaceable.

The signal is stable and reliable: the new NB-loT/LoRa wireless data transmission technology is adopted.

Electronic sampling: sampling 1L, 10L, or 100L.

Optional materials: ductile iron, engineering plastics, copper, stainless steel.

Environmental level: Class B electromagnetic environment: E1

Temperature class: T30, T90

Accuracy Class: Class 2

Maximum Permissible Error

Maximum permissible error: low zone (Q1≤Q< Q2) maximum permissible error is ±5%

When the water temperature is less than or equal to 30C, the maximum permissible error in the high zone (Q2≤Q≤Q4) is ±2%; when the water temperature is> 30C, the maximum permissible error in the high zone (Q2≤Q≤Q4) is ±3%
