The ultrasonic remote water meter has no moving parts, and there are no internal flow blocking devices that will not cause pressure loss. By making the dynamic flow rate low and the range wide, the pipe section ultrasonic water meter can eliminate a large number of negative problems of traditional water meters and facilitate control. Dual channel ultrasonic water meters are widely used in urban and rural water supply and water management monitoring

Manufacturer of Large caliber ultrasonic intelligent water meter

The ultrasonic water meter adopts a newly developed unique ultrasonic propagation phase and time difference measurement technology, using a dual channel ultrasonic measurement method. It has significant characteristics such as high accuracy, low power consumption, wide measurement range, and stability and reliability. The water meter has reached IP68 protection level and is widely applicable in various situations. Solve the problems of traditional water meters running idle, not measuring small flow rates, and excessive pressure loss.

characteristic

1. By using ultrasonic flow measurement technology, there are no mechanical rotating parts, resulting in low pressure loss and reduced power consumption of the water pump, thus reducing the cost of water supply for enterprises.
2. Adopting a dual channel measurement method can achieve higher accuracy and reliability within the measurement range, and can work at any flow point for a long time with strong resistance to electromagnetic interference.
3. Adopting a low-power design scheme, a single battery can work continuously for more than 6 years.
4. Low initial traffic, high degree level.
5. Having redundancy, even if one of the channels is blocked by foreign objects or abnormal, the entire meter can still measure normally
6. Self diagnostic function: flow sensor fault alarm, temperature sensor open circuit and short circuit alarm, measurement over limit alarm, battery undervoltage alarm.
7. Optional pressure sensor for monitoring water supply pressure in the pipeline network
8. Optional electric valve, remote control valve switch.
9. Equipped with RS-485 Multiple optional communication methods such as M-BUS, NB IoT, LoRa, LoRaWAN, etc.
