Introduction


QWM12 split-type prepaid smart water meter features a split meter & CIU layout, available in DN15, DN20 and DN25 dimensions, enabling indoor top-up with the measuring body installed outdoors. Equipped with reliable wireless signal delivery and flexible system integration capacity, it delivers a robust all-in-one metering solution for municipal water utility operations.

Decoupled RF Wireless Topology: Features long-distance wireless signal transmission and a data repeater mesh on each meter terminal, significantly expanding the reliable reading and token delivery range to remote CIU endpoints.
Adaptable Sizing Matrix: Scalable housing frameworks available across DN15 (165mm length), DN20 (195mm length), and DN25 (225mm length) to perfectly match varying connection threads (G3/4B, G1B, G11/4B).
Rigid Revenue Vault Controls: Outfitted with customizable hoarding limit thresholds to prevent malicious speculative water stockpiling, alongside integrated audio-visual low-credit warnings that nudge tenants to buy vouchers before auto-shutoff occurs.



Standards

  • ISO 4064:2005
  • IEC 62055

Main Function


1. Prepayment function: purchase first, water consumption next.
2. Multi-tariff function (optional): two optional multi-tariff billing modes, by the unit of water amount or monetary currency.
3. Checking function: the status and historical consumption information can be read.
4. Alarming function: alarm users to purchase water in time, as the valve will be closed when the residual water is insufficient.
5. Hoarding limit function: program the hoarding limit to prevent malicious hoarding.
6. Valve self-maintenance function: the meter will open and close the valve automatically once every 15 days.
7. Battery self-maintenance function: the battery will be activated at least once every 7 days.
8. Battery low voltage detection: low voltage detection device is fixed inside; if low power <= 3.0V, then close the valve, and the battery symbol will display on the LCD.
9. Low power consumption circuit, long battery life with battery voltage measurable.
10. Long-distance wireless transmission, high rate of success.
11. Remote auto valve control for meters with value control function.
12. Networking and data repeater function on each meter, expands the wireless reading range.
13. Monthly and accumulated water consumption data can be read to meet various management requirements.
14. Wireless parameters, meter address, and base register can be registered and programmed through special equipment; easy installation, configuration and management.
15. Flexible and efficient hand-held wireless reading modes: single reading mode and batch reading mode.
