Flowmasonic WUF 100 J Portable Ultrasonic Flow Meter

Description

The Flowmasonic WUF100J transit time portable flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. To install the sensor is to clamp the transducer on the outer surface of the pipe with a specified distance. The transducers ultrasonic can be mounted in V-method where the sound transverses the pipe twice. The Other method is Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once.

This selection of the mounting method depends on pipe and liquid characteristics. The Flowmasonic flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers. The difference in the transit time measured is directly and exactly related to the velocity of the liquid in the pipe, show as follows.
