DVD Ultrasonic Watermeters read water flow by the help of two ultrasonic probes positioned in the same axis.
In case of a velocity change, variance in ultrasonic waves is detected by the probe and by the help of the processor; these variances are converted into flow rate data.
Flowrate and Consumption Values can be read from the IP68 protected LED Screen.
Furthermore, it provides an alarm in low battery conditions. Internal Lithium Battery can provide power up to 10 years autonomously.
As for communications, the meter has an M-Bus and Optic interface as standard and Pulse or RF interface can be provided optionally.
