Ultrasonic Water Meter

Product Description

Ultrasonic Water meter--The ultrasonic water meter use a pair of transducer to send and recieve the ultrasonic sound waves through the fluid to determine the velocity and translate the velocity into measurement of the water volume.

Accuracy	2%
Repeatability	Better than 0.5%
Measurement Period	3 seconds by default. 1~31second optionally.
Display	Low power consumption LCD displaying: • Positive, Negative tantalizer, instantaneous flow rate, velocity, total working time, date, and working status. • Battery terminal voltage, ultrasonic signal strength, signal quality.
