Capacitance Based Level Sensor
Ultrasonic level or distance sensors can be designed as Continuous level or distance measurement sensors and are typically used to measure the time taken for an acoustic wave to propagate through a fluid. From knowledge of the speed of sound in the fluid, the distance can be calculated.
Ultrasonic level/distance sensors inherently offer a number of reliability advantages over other types of sensors. These include operational tolerance to sediment, foam and fluid opacity, making them ideal in applications where sensing levels (or height) of fuel, chemicals, additives or reactants is required.
