Wireless Ultrasonic Water Meter Intelligent Digital
In order to solve the problems of wireless remote meter reading and easy wear and tear of water supply management enterprises, S.H.Meters has developed and launched a new type of electronic water meter - an ultrasonic water meter.
Main Feature
The turndown ratio is 400:1, and the starting flow is small.
IP68 waterproof grade can work in water for a long time.
An advanced multi-function, ultra-low power consumption microprocessor is selected. Optimized measures are adopted from both software and hardware design to ensure the calculator has a long life, low power consumption, stable operation, and a strong ability to resist electromagnetic interference.
It has the functions of self-diagnosis, fault display, and power-off data protection. When the ultrasonic water meter fails occasionally, it will display the fault code to help identify the source of the fault.
With infrared, M-BUS, RS485, and other communication functions, it can realize remote data transmission and centralized control.
Built-in environmentally friendly high-energy lithium battery pack, with a working life of more than 6 years.
Conditions of Use
Working environment temperature: 0.1℃-30℃
Ambient humidity: (0-100)%RH
Wiring method: M-BUS, RS485
Transmission rate: 2400bps
Accuracy level: level 2

Structure of ultrasonic water meter
Ultrasonic metering module, sound channel, probe, transducer, the measurement chamber
Ultrasonic metering module: used to calculate the speed difference between the transmission of sound waves in water, so as to calculate the flow rate
Sound channel, probe: send and receive ultrasonic signals
Transducer: The device to convert electrical, mechanical, or acoustic energy from one form of energy to another is called a transducer, also known as an active transducer. The high-performance transducer can reduce the number of acoustic waves and minimize power consumption.
Measuring cavity: as the carrier of measurement (large diameter using the reduced design)
