Description
|
When
an ultrasonic wave travels in a liquid, the flow of the
liquid will cause its speed to change.
When it travels in the flow direction, its
speed increases and against it, it decreases.
By measuring the difference in travel
times between both directions, one can measure the flow
speed.
As shown in Chart 1, a pair of
sensors are mounted upstream and downstream on the surface
of the pipe.
Its mounting configuration
can be 'Z' or 'V'. The
time difference of ultrasonic signals transmitted and
received across upstream and downstream
are calculated as below;
