Product Details

Wafer type Ultrasonic water meter for industrial irrigation hydrometer Communication: Mbus

Description:

The Ultrasonic water meters use sound waves to determine the velocity of a fluid flowing in a pipe. At no flow conditions, the frequencies of an ultrasonic wave transmitted into a pipe and its reflections from the fluid are the same. Under flowing conditions, the frequency of the reflected wave is different due to the Doppler effect. When the fluid moves faster, the frequency shift increases linearly. The transmitter processes signals from the transmitted wave and its reflections to determine the flow rate.

Superior hydraulic design, no moving parts, nothing mechanical to maintain

Extremely wide turndown ratio (R=500: 1)
Super low pressure loss
Battery powered -- above 10 years or up to 20 years life expectancy
Extremely sensitive and accurate in low flows
Available sizes: DN15-DN300
