Ultrasonic water meters are composed of flow sensors, temperature sensors, computers (integrators) and other components. It features in compact structure and convenient installation. It uses high-quality piezoceramic transducers ensures high accuracy and stability; there is no mechanical movement, no wear and tear, it is not easily affected by poor water quality and has low maintenance costs. It has the features of using a picosecond-level high-precision chip, high measurement accuracy, small starting flow rate, and the ability to realize dripping water measurement.
Ultrasonic Water Meter
Description
Features
NB-IOT communication technology, low power consumption, wide coverage, remote maintenance;
The valve core and sealing components of the valve control water meter adopt innovative technology processing and surface treatment processes to ensure that the valve parts work normally and stably for a long time when corrosion and scaling are prone to a lot of impurities;
It has remote valve control function, enhances the control of water companies, effectively shortens the time for water bill payment, and can also realize pre-charge;
Low starting flow rate can reach 6mm/s;
Wide range ratio, range ratio ≥250, up to R400;
The whole machine IP68 protection level can be used for long-term water immersion;
Automatically make up the report to ensure the integrity of the reported data;
Micropower consumption, built-in 3.6V lithium battery, can work continuously for more than 10 years;
Instant alarms can effectively monitor the operating status of pipelines and water meters;
The water meter has small size, high stability and strong anti-interference ability;
Using a butterfly valve with a gear reducer motor, long service life and low leakage (less than 0.005m3/h);
Low pressure loss, ultrasonic measurement technology can be used to minimize pressure loss in multi-angle installation pipelines.
Application
Built-in antennas are often used in new & old communities to intelligently renovate pipeline water well houses
External antennas are often used in underground wells, new communities with poor signals, and old communities to intelligently renovate pipeline water well houses
Meet the metering and settlement needs of water company for end users.
