◆System architecture:

1 Functional Features

1.1 Adopting non-magnetic measurement technology, the mechanical part is separated from the electronic module for easy on-site installation or disassembly.

1.2 Keep the mechanical display mode for users to visually check the water consumption.

1.3 Electronic readings can be automatically uploaded to the server through NB IoT communication, enabling remote data monitoring.

1.4 Adopting NB IoT wireless communication technology, it is easy to install and does not require wiring.

When the mechanical reading cannot be read normally or the battery level is low, the water meter will actively upload the abnormal status to remind the management department that the water meter has malfunctioned.

2 Main technical parameters

2.1 Maximum allowable working pressure: equal to 1.0MPa.

2.2 Maximum allowable working temperature: The cold water meter is 30 ℃.

2.3 Measurement Characteristics

2.3.1 Level 2 Water Meter (Accuracy Level 2)

2.3.2 Within the temperature range of 0.1 ℃ to 30 ℃, the maximum allowable error of the water meter is ± 2% in the high zone (Q2 ≤ Q ≤ Q4) and ± 5% in the low zone (Q1 ≤ Q ＜ Q2).
