Products Description

product-1200-550

No Moving Parts, high accuracy for years long. No moving components in the flow sensor, avoid long-term abrasion of mechanical parts which may result in inaccuracy measurement and failure of the meter. Such design is also resistant to impurities, therefore no inspections and maintenance are cost-free.

The ultrasonic water meter collects sound waves and uses a calculation formula to obtain the amount of water flowing through the water meter per unit time to calculate the water flow rate to obtain the cumulative flow of water.

Product Features

Ultrasonic signal quality detection

Support prepaid function, remote recharge, and control valve through account balance

Overall IP68 design, long-term immersion in work

Low starting flow, the minimum flow is lower than 1/3 of the traditional water meter

Water temperature detection, temperature alarm

Communication

The LoRaWAN and NB-IoT standards are both parts of a larger family of technologies known as LPWAN (Low Power Wide Area Networking).

LoRaWAN is an open protocol offered by the LoRa alliance that uses an unlicensed spectrum, allowing almost anyone to set up their networks at a low cost.

NB-IoT is a licensed protocol from the standards organization 3GPP offered through the licensed RF spectrum, making it available only through established mobile network operators.
