Ultrasonic Fluid Level Sensors from APC International!

Ultrasonic fluid level sensors can be used to monitor fluid levels in a wide variety of commercial and industrial applications. Piezo level sensors work by monitoring the acoustic coupling level between an ultrasonic transmitter and an ultrasonic receiver. When there is liquid between the transmitting transducer and the receiving transducer, acoustic coupling is high. When the fluid level falls and air occupies the signal path, coupling is low and an output signal will be generated to indicate that the fluid level has dropped to below the level of the transducers.

Figure 5.43 from our book Piezoelectric Ceramics:Principles and Applications

shows one design style for an ultrasonic level indicator. Levels can

also be detected using the time of flight and reflection method.

Fluid level sensors are keyed to the difference in ultrasound transmission through the liquid being monitored versus ultrasound transmission through air. These piezoelectric sensors can monitor levels of liquids that exhibit a wide range of complexity and viscosity, from water and gasoline to oil and hydraulic fluids.

Looking for more detailed level information? Use time of flight and a reflection from the surface of the liquid.
