Ultrasonic Level Transmitter works on the principle of High Frequency sound wave travel time calculation. A high frequency sound wave emitted from a transmitter mounted inside a transducer hits the liquid surface, the time taken for the wave to return to receiver mounted inside the transducer will be proportional to liquid level.
Ultrasonic Level Transmitter is used for water, oil, chemical, diesel, beverage, juice, solvent and fuel level measurement.
It is not suitable for liquid having high fume density, foam and highly turbulent surface.
