NB Wireless Level Transmitter

Deep Coverage · Ultra-Low Power Consumption —— The Ultimate Solution for IoT Liquid Level Monitoring

YUNYI NB Wireless Level Gauge is an intelligent liquid level monitoring device based on NB-IoT (Narrowband IoT) communication technology. It employs high-precision sensors to collect liquid level data, which is directly uploaded to the cloud platform via the carrier’s NB-IoT network, ensuring long-term stable operation under wide-area deep coverage. Featuring an IP68 protection rating and an extended battery life of 5-10 years, the device is specifically designed for liquid level monitoring in industrial environments lacking mains power supply, characterized by dispersed locations and harsh conditions. It represents the optimal choice for building large-scale IoT liquid level monitoring systems.
