Ultrasonic Water Meter
We are autorised channel partner of SSTPL (Sehaj Synergy Technologies Private Limited) for Smart water meter
LoRa Enabled Ultrasonic water meter supports standard LoRaWAN™ protocol. The ultrasonic water meter is an all-electronic water meter obtaining water flow rate by analyzing and processing water speed by detecting the time difference caused by the change of velocity when the ultrasonic beam propagates along or adverse current. It has the characteristics of low start-up flow rate, wide range ratio and high measurement accuracy. Without movable parts and flow resistant elements in the meter body, as well as impact of impurities in the water, the meter has a long service life.
