--Product Description
Product Introduction：
Ultrasonic water meter is an intelligent flow meter, which can accurately measure the flow.The products are characterized by beautiful appearance, convenient installation, accurate measurement, stable operation, strong anti-pollution and anti-corrosion ability, long service life, small pressure loss, economic and practical, etc., suitable for domestic water, central air conditioning system water flow metering charges.
Product Appearance：
（Non-valve controlled small diameter ultrasonic smart meter）
Principle of Ultrasonic Water Meter：
It mainly consists of temperature sensor, flow sensor and calculator.The temperature sensor measures the temperature of water, and the flow sensor measures the volume of water flowing through the pipeline through the time difference. These two data are collected and sent to the integral calculator to calculate the amount of water used, store and display.

After the communication module is superimposed, if combined with the integrated energy
control platform software independently developed by the company，It can realize：
* Unmanned, reduced manpower.
●automatic data logging.
●Industrial-grade communication equipment ensures the safety and reliability of meter reading.
●Complete system log traceability is available.
●Visual graphics, data statistics.
●Meter status alarm；When low-power and low-volume magnetic attack sampling fault leakage alarm (external leakage alarm) occurs,
real-time alarm information is uploaded to the background application platform.
●Control the gasmeter valve switch through background application software (desktop WEB and mobile APP).
●When the meteris removed or attacked by external forces, the information will be transmitted to the background application
platform in real time
●The stability of data transmission can be monitored.
