Flow vs differential pressure relationship

WebOct 13, 2010 · In simple terms, the mathematical constant 2.31 converts a unit of energy against gravity into a unit of force against any other area. This constant converts a foot of head of water into pressure: Head in feet of water divided by 2.31 equals pressure in psi, and pressure in psi times 2.31 equals head in feet.

WebThe pressure recovery is limited for an orifice plate and the permanent pressure loss depends primarily on the area ratio. For an area ratio of 0.5 the head loss is about 70 - 75% of the orifice differential.. The orifice meter is recommended for clean and dirty liquids and some slurry services. Web4.4.1 Differential pressure flow sensors. Differential pressure sensors operate on the general principle that the pressure drop across the meter is proportional to the square of the flow rate. Multiple pressure sensors, covered earlier in the chapter, are used to measure this pressure differential.
