 Microwave
Phase Difference
Microwave phase difference exploits the way a fluid's density
affects the propagation of microwaves when they pass through
it. This allows a reliable measurement of the fluid's density
by monitoring the difference in microwave phase between the
original wave and the one that passed through the measured fluid.
Measuring fluid density by observing a wave's phase difference
is unaffected by flow velocity and/or is not affected by the
contamination and/or bubbles. This technology is effective in
various applications where determining the consistency of suspended
solids, slurries, and sludge is necessary such, as in the pulp
and paper and wastewater industries.
