Introduction
1.The SLMFR uses LoRa communication, the LoRaWAN communication protocol is available.
2.It can transmit information at very low frequencies at low complexity andcost. Also it's an ultra-remote, low-power, high-availability and low-cost communication technology that can be used in different regions.
3.SLMFR adopts the ultrasonic transit time measurement principle, combined with the patented flow algorithmtechnology, it realizes accurate measurement of the fluid flow in the pipe.
