The ultrasonic water meter operates on ultrasonic transit-time measurement technology. It uses advanced signal processing to calculate the difference in travel time of ultrasonic waves, resulting in highly precise velocity measurement. This device combines measurement, calculation, and display functions and utilizes micro-power technology, allowing a single battery to last for over 6 years. By default, it uses plate number 1, but we can accommodate special requirements with plate number 2. It can accurately measure a minimum flow rate of 0.01 m³/h, meeting the international standard OIML R49/MID. Additionally, this instrument is compact, highly stable, and resistant to interference.
