Ultrasonic Flow Meters

Transit-time ultrasonic flow meters measure the time a signal transmits from the first transducer until the second transducer receives it. The meter takes time measurements in both directions, with and against the flow. The time measurements will be the same in both directions If there is no flow in the pipe. With flow in the line, the sound waves will move faster, traveling with the flow and slower traveling against the flow.  The meter calculates liquid velocity from the difference in these two time measurements. With the area of the pipe and velocity known, the meter can calculate the volumetric flow rate.

SonoPro® ultrasonic flowmeters incorporate high accuracy transit-time ultrasonic technology to deliver accurate and reliable flow metering. The innovative design includes matched precision transducers and signal processing circuitry to accurately measure the flow of most liquids over a wide range of velocities.

SonoPro® meters are available with insertion or clamp-on transducers. Clamp-on meters have no wear, create zero pressure loss, and do not require process interruptions to install them since they are attached to the outside of the pipe.

SonoPro® meters can provide a reliable (BTU) energy measurement with external temperature input.
