To measure and adjust air flow in air valves, diffusers or grilles accurate measurement of small pressure drop (differential pressure) is often required (usually in the range of -50 to 50 Pa).

How do you convert an air velocity measurement to a volumetric flow rate? It is important to understand the various formulas and technical definitions to prevent errors in calculation. Volumetric flow ...

Abstract: There are various differential pressure methods to measure the air flow rate in a closed duct. These methods are defined by ISO standards, thus providing measurement with high accuracy.

Everybody is familiar with pressure. Not the figurative type, of course: looming deadlines and impossible-to-hit metrics. Rather, the literal, scientific force; that is the pressure exerted by fluids ...

Utilizing an orifice plate installed in a pipe and accurately measuring the differential pressure (DP) to calculate flow is one of most common methods in the chemical process industries (CPI) (Figure ...
