Operating PrincipleTransit Time Ultrasonic Flow Meter (Time of Flight)

Typically operate within 1-2 MHz frequencies Pair of transducers, each containing a piezo-electric crystalOne transducer transmits sound while the other acts as a receiverSignal transmitted upstream against the flowThen signal transmitted downstream

Operating Principle

Difference in time is proportional to the flow velocityFlow volume is calculated by multiplying velocity by the cross-sectional areaTransit time ultrasonic is for clean liquids onlyParticles disrupt signal

Selection

Ultrasonic Flow Meter Selection (Key questions)

Does the liquid have particulates of 100 ppm of 100 microns in size? Clean water < 3% (<12% UXF3) particulates content?Maximum and minimum flow rate for the process?Process temperature minimum and maximum?Is the pipe always full? (a must)Straight pipe recommendations met?Is it a coating/viscous liquid? (avoid)
