1. Bluetooth communication: Bluetooth water meter is a smart water meter with Bluetooth communication channel. It can be connected to a mobile phone with Bluetooth interface and the meter can be recharged through the mobile phone APP.
2. Prepayment function: users buy water first and then use it. If the payment is in arrears, the valve will be closed and the water supply will be cut off.
3. Dual display function: LCD displays the accumulated water volume synchronously with the character wheel reading to avoid disputes caused by LCD display failure.
4. Automatic valve maintenance function: The valve rotates regularly to clean the valve scale and prevent valve failure.
5. Anti-hoarding function: The software can flexibly set the recharge limit to prevent users from hoarding water.
6. Waterproof design: The six-way waterproof design effectively protects the normal operation of the electronic compartment and mechanical parts, copes with the harsh installation environment on site, and greatly improves the service life.
7. Alarm function: battery low voltage alarm, insufficient water usage alarm, strong magnetic interference alarm, arrears alarm, water valve failure alarm, etc.
8. Use a pressure-loss-free motor with large output torque to control the valve.
9. Valve abnormality metering function: If the valve fails and cannot be shut off, the water meter will switch to cumulative overdraft metering. When purchasing water again, the water meter will automatically deduct the overdraft water volume.
10. Anti-strong magnetic interference function: When the normal measurement of the water meter is disturbed by strong magnetism, the water meter can automatically shut off the valve and cut off the water supply. After the water meter detects that the magnetic interference disappears, the water supply can be restored by swiping the card.
11. Device binding: The same mobile phone can be bound to multiple Bluetooth water meters, and recharge and query them. The same Bluetooth water meter can be bound to different mobile phones.
12. Low power consumption design, using large-capacity lithium battery, longer service life.
