The working principle of ultrasonic water meter without valve is basically the same as that of valve-controlled ultrasonic water meter, except that there is no control valve. This water meter is suitable for application scenarios that do not require the on/off valve function. This water meter has a lower cost than valve-controlled ultrasonic water meter. If there is no on/off valve requirement, then this water meter is the most reasonable choice.
Parameter of Ultrasonic Water Meters Without Valve | |
1. The power consumption of the whole meter is very low, and the built-in 3.6V 8500mAh lithium battery can be used for 10 years.
2. Ultra-high range ratio, up to 800:1. (can be customized according to your needs)
3. Multiple communication options (NB-IoT, LoRaWAN, 4G, M-Bus, RS485, GPRS, etc.)
4. IP68 waterproof level, can be installed in water
5. Extremely low initial flow, can achieve drip metering, so that every drop of water is under control.
6. Forward and reverse measurement.
7. 4 times high-speed measurements per second.
8. The installation can be horizontal or vertical, which is easy to construct.
9. With self-diagnosis function, flow sensor fault alarm, measurement over range alarm, and battery low voltage alarm.
10. Food-grade materials, will not affect the quality of drinking water, to ensure drinking water safety.
