Portable Ultrasonic Flow Meter 

Model TUF 2000 H

TUF 2000 H

METHODOLOGY

    • Using clamp-on, transit time flow measurement the flow rate of the liquid inside the pipe is measured by a pair of ultrasonic flow sensors on the outside of the pipe.

    • Liquid should fill the pipe and should contain very little particles or bubbles.

    • Operation is 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, as shown in the following figure.

Ultrasonic sensor diagram
θ is the angle between the sound path and the flow direction
M is the number of times the sound traverses the flow
D is the pipe diameter
T up is the time for the beam travelling from upstream the transducer to the downstream transducer
T down is the time for the beam travelling from the downstream transducer to the upstream transducer
ΔT = Tup – Tdown
