Ultra low power ultrasonic water meter

>

Time difference measurement principle
The principle of ultrasonic time difference method, patented dual balanced transmission and reception signal processing. High precision, good reliability, no moving parts, no need to set parameters, and can be installed at any angle.
Measurement accuracy: ± 1%, ± 2%, ± 3% optional, with repeatability better than ± 0.5%
Two wire system or battery powered, with ultra-low power consumption, can work continuously for 6-10 years using battery power.
Ultra low starting flow rate, with a low measurable fluid velocity of 0.01m/s.
No pressure loss or moving parts, 10-year maintenance free design.
The length of the pipe section is designed according to the specifications and dimensions of a regular water meter
Designed with an IP68 protection level, it can operate normally at 2 meters underwater.
High temperature wear-resistant ceramic sensor, suitable for temperatures ranging from -40 to 160 ℃
Measurement medium: water and other liquid levels.
Interface output: 4-20mA, RS232, RS485. Standard M-BUS communication protocol.
Automatic loop display of cumulative, instantaneous, flow rate, and working time results, programmable, and can be displayed in top-down, head up, or split view.
The patented dual balanced 20dB dynamic ultrasonic adaptive receiving circuit ensures reliable operation even when the state deteriorates.
