Ultrasonic water meter
Ultrasonic water meter is a new type of water meter that detects the time difference caused by the change of the speed when the ultrasonic beam propagates in the opposite direction of the water, and analyzes the flow rate of the water to further calculate the flow rate of the water.Features: low starting flow rate, wide range ratio, high measurement accuracy and stable operation.The internal non-moving parts have no obstruction elements, are not affected by impurities in the water, and have a long service life. The output communication function is complete, meeting various communication and wireless networking requirements.It has excellent small flow detection capability, can solve many traditional water meter problems, is more suitable for water fee gradient charging, and is more suitable for water resource conservation and rational utilization.

Ultrasonic water meterfeatures:
1. Measurement is stable, accurate, horizontal installation, vertical installation, can ensure accurate measurement2. The ultrasonic water meter head can be rotated 360 degrees horizontally or 90 degrees vertically. The reading is convenient.3. It can be installed horizontally or vertically. The factory default installation is in the inlet pipe (if it needs to be installed in the return pipe, please explain in advance)4. Optional RS485 bus and M-Bus bus output interface. Realize data remote transmission, centralized control5. Under voltage alarm6. Automatic data error correction technology7. Can install GPRS, data timing GPRS upload function, suitable for a variety of installation environments8. Flow sensor fault alarm9. High definition wide temperature LCD display10. With photoelectric interface, infrared meter reading tool can realize on-site meter reading11. Remote monitoring: remote meter reading12. Convenient installation: stable and accurate measurement, horizontal installation and vertical installation (required for vertical installation)13. Long service life: large-capacity battery power supply, low-power circuit design, service life greater than 6 years14. High protection level: IP68 high protection level design, can work in harsh environments15. A variety of interfaces, protocol output: MBUS / 485 interface, GPRS remote transmission, etc., convenient for users to use in different occasions
