Ultrasonic Level Monitor
The Ultrasonic Level Meter provides a reliable non-contact solution for monitoring material levels in tanks, vessels, and open channels. It uses ultrasonic technology to detect the surface of liquids, solids, and slurries without direct contact with the measured medium. With multiple communication options, including 4G, WiFi, LoRaWAN, and LoRa, the device is suitable for both local monitoring and remote IoT applications.
