Ultrasonic Water Meter
It is an advanced and highly accurate ultrasonic water meter. With no moving parts, used for measurement of cold water consumption for residential applications.
The ultrasonic water measurement is based on the transit time method, and all measurements, references, readings, calculations and data communication is controlled by an advanced specially designed electronics circuit.
The meter has no moving parts, presents an IP68 register, and with big and full information LCD, easy to read the data and see the alarms.
