The ELT Ultrasonic is designed for measuring the distance. It can be placed in various environments and can work as a bin level sensor, tank level sensor, or water level under bridges, for example.
Not only can you measure distance with the ELT Ultrasonic, but it also has four internal sensors: temperature sensor, humidity sensor, accelerometer, and an atmospheric pressure sensor. It is enclosed in an IP67 box which makes it ideal for mounting outside or in extreme conditions.
