Smart ultrasonic water meterMeasures the amount of water using the difference in the transmission time of two ultrasonic sensors.
W-type sensing minimizes the degradation and error of water flow, which are the drawbacks of existing products.
Maximizes the reliability and precision of measurement.
The round hole structure minimizes vortex and air bubbles.
High accuracy (Q3/Q1=250 )
Since the equipment does not have mechanical parts, deterioration of measurement performance due to wear is prevented.
IP68 rating
Prevents damage due to freezing by strengthening water pressure and warming effect.
Battery life: ≥ 12 years
Thanks to using stainless steel inside the water pipe, the stability of drinking water quality is ensured and
the harmful components of the water meter are completely removed.
