Wireless remote ultrasonic water meter

By measuring the velocity change of ultrasonic wave propagation in pipeline water flow, the velocity of water flow is deduced, and then the passing water flow is calculated. Equipped with Nb IOT mobile Internet of things module, it can realize the remote timing transmission and management of data according to the preset management strategy.

Flow error curve

Pressure loss curve

  1. The starting flow is small and the range ratio is wide;

  2. It can record forward flow and reverse flow, with high measurement accuracy, and stable and long-lasting;

  3. There are no moving parts in the pipeline, the pressure loss is small, and there is no component wear;

  4. Low-power circuit design, long battery life;

  5. It can be installed at any angle, and it is not required to be horizontal or vertical;

  6. Strengthen the design of waterproof protection, the protection level of the whole machine reaches IP68, and it can be installed in the surface well;

  7. Large-capacity data storage, record complete operating information, including 36-month time-sharing usage information;

  8. Completely independent NB-IoT IoT communication module design, easy to separate maintenance and replacement;

  9. It is designed with an active trigger to upload data button, and emergency data upload or communication test when available.
