pressure of the liquid. The impact pressure is directly proportional to the flow rate of the liquid.
As the liquid flows around the Tek-DP 1650A DProbar, the static pressure ports measure the
decrease in pressure downstream of the flow. These pressure differentials are then averaged to
determine the flow rate of the liquid using the following formulas:
To calculate the volumetric flow rate:
