Product Description
The ultrasonic water meter(7310) is a modern intelligent instrument that uses ultrasonic technology to measure water flow. It precisely measures the speed and flow rate of water by emitting and receiving ultrasonic signals.
Product Features
1. There are no mechanical friction components, which reduces wear and tear.
2. The stable and reliable design ensures long-term efficient operation of the device.
3. It can still accurately measure water usage at a low flow rate of 4L/h.
4. It can accurately record the total water consumption. Record total volume as small as 1mL.
5. The 9-digit LCD screen provides real-time data display.
6. With a low-power circuit design, the device achieves a lifespan of up to 12 years.
7. Ready for AMR with wired and wireless communication technologies.
8. The bidirectional metering function allows measurement of both forward and reverse flow.
9. The maximum displayable water volume is 9999 m³ (higher values can be set).
10. Provides higher precision in water flow measurement.
