Small-caliber Household Ultrasonic Water Meter

The ultrasonic water meter uses the calculation formula to obtain the amount of water flowing through the water meter per unit time by collecting sound waves to calculate the flow rate of the water to obtain the cumulative flow of water. And it can also transmit data remotely through the M-BUS bus. If the installation location is not easy to wire, you can also use LoRa wireless or NB-IoT wireless ultrasonic water meters for wireless data collection.

Instructions for use

LoRa

It uses a free public wireless frequency band, and the lora concentrator is required. (The repeater is optional depending on the on-site environment)

NB-IoT

It uses authorized wireless frequency bands and uses operator networks. Need to lay the NB-IOT base station on site
