WATER METER NEXTRON DN15 in one solution ultrasonic WATER METER adopts the principle of ultrasonic wave, which is a kind of water meter that can further calculate the flow rate of WATER by detecting the time difference caused by the charge of speed when the ultrasonic sound beam propagates downstream and countercurrently in the water, analyzes and processes the flow rate of water.

PERFORMANCE CHARACTERISTICS WATER METER NEXTRON DN15 :
- ACCURACY
- Small starting flow, high range ratio, up to R250
- MICRO POWER CONSUMPTION
- Adopt micro-power consumption design to minimize the comprehensive power consumption of the water meter
- SERVICE LIFE
- No mechanical wear of moving parts in Service life meters, which can be used stably and reliably for a long time
- COMMU NICATIONS
- NB-IOT, LoRa LoRaWAN-Bus,RS485, Pulst output
