Interpreting Flow Data
The following graphs offer the pressure losses for the monitor (and other devices) in terms of
Total Static Pressure Drop. This Total Static Pressure Drop can be found by measuring the
difference between the static inlet pressure and the static outlet pressure. The static
pressure at either of these points can be found using a simple pressure gauge. An
illustration of this method can be seen below.
In mathematical terms, the Total Static Pressure Drop is the change in Velocity Pressure
plus Friction Loss. The change in Velocity Pressure results from the change in velocity of
water caused by the change in the cross section of a waterway. Friction Loss results from
the drag and sidewall interference of the water through a device. A simple equation can be
seen below.
