Micronics Clamp-On, non-invasive
meters and portable instruments
measure the flow of liquid within a
pipeline through two sound
transmitter/receivers clamped to the
outside of the pipe wall. The sound
is directed through the pipe wall into
the flowing liquid where the speed of
the sound wave is modulated by the
flowing liquid. The modulation is
converted into volume flow rate by
the electronics in the flow meter.

There are no mechanical moving
parts required to make the
measurement. The ultrasonic meter
does not penetrate into the liquid
and as a consequence is said to be
cheaper to manufacture than
alternative in-line aseptic meters.

It solves flow-metering problems
by eliminating any possibility of
contamination.
