RF card smart water meter (Bluetooth)

Prepaid water meter is a new type of measuring instrument that uses a new microprocessor to collect, process, display, and store water volume.

Multi flow rotor type: adopting the mainstream domestic measurement structure.

Liquid sealed movement: high sensitivity; The special liquid packaging of the character wheel window can maintain clear readings.

Dry type movement: center magnetic drive, anti magnetic interference, good stability, strong frost resistance, clear reading.

Prepaid function, pay first, use later.

Support tiered water pricing and multiple meters per card.

Anti external magnetic interference function, low power consumption, and long usage time.

The enclosure protection level is IP68.

Material options: ductile iron, engineering plastics, copper, stainless steel. ..

Environmental grade: Class B Electromagnetic environment: E1

Temperature Class: T30, T90

Accuracy level: Level 2

The allowable error for the low zone (Q1 ≤ Q<Q2) is ± 5%

When the water temperature is ≤ 30C, the allowable error in the high zone (Q2 ≤ Q ≤ Q4) is ± 2%; When the water temperature is above 30 ° C, the allowable error for the high zone (Q2 ≤ Q ≤ Q4) is ± 3%
