ULTRASONIC LEVEL SENSOR (ISL LM1100)
The ISL LM1100 Ultrasonic Level Sensor is a flexible and configurable, battery operated, ultrasonic level sensor with an integrated LoRaWAN radio.
The ISL LM1100 Ultrasonic Level Sensor can be used to monitor a wide range of liquids, including fuel (oil & kerosene), water, waste oil and more.
With remote monitoring via LoRaWAN networks, this helps you ensure continued supply and optimise delivery or collections. The ISL LM1100 Ultrasonic Level Sensor includes low and high alarms for edge intelligence.
