The Ellenex DUS3-L Ultrasonic Distance and Level Transmitter is a battery-powered non-contact ultrasonic sensor that measures distance and level over LoRaWAN. With no wetted parts it suits both liquid and solid media — silos, open channels, tanks and bins — and installs above the target with a simple bracket mount.
