In some situation, conventional method of level measurement for liquids and solids are not effective, difficult or impossible:
- when the product is aggressive
- when the tank is not easily accessible

- for high temperature, dusty environment and uneven surface
How it works
In brief, the sensor sends pulsed radar waves or frequency-modulated continuous waves. By measuring the delay between the transmittal and the receipt of the signal, the sensor is able to determine the distance.
