Continuous level measurement with level sensors
In continuous level measurement, the level of a medium in a tank or silo is detected with the help of different measuring methods and converted into an electronic signal. The level signal is either displayed directly on site or incorporated into a process control or management system. Typical applications for continuous level measurement are process tanks, storage tanks or silos in the process industry.
Level measurement with radar
In continuous non-contact level measurement with radar, the sensor sends microwave signals towards the medium from above. The surface of the medium reflects the signals back in the direction of the sensor. Using the received microwave signals, the sensor determines the distance to the product surface and calculates the level from it. Liquids and solids are commonly measured with this measuring technique.
Level measurement with ultrasonic
In non-contact ultrasonic level measurement, the sensor emits ultrasonic pulses in the direction of the medium, which then reflects them back. The elapsed time from emission to reception of the signals is proportional to the level in the tank. Ultrasonic sensors are ideal for simple standard applications, both for liquids and for solids.
