Ultrasonic sensing utilizing Time Of Flight (TOF) measurement techniques can be used to monitor material purity/contamination levels and or to differentiate materials non-invasively. This technology has been utilized in the automotive, consumer, medical and food preparation markets worldwide. Ultrasonic (TOF) sensing can yield high accuracy with low power consumption for all of these markets. This Application Note will demonstrate such measurements utilizing TI’s TDC1000 Ultrasonic Analog Front End and an inexpensive “test cell” for a variety of automotive fluids.
