Flow calculation using differential pressure
WebAs one of the most common technologies for measuring flow, differential pressure (DP) flow has a long history of achieving high accuracy and durability. This measurement technology enables compensated flow, … WebAlso Read : Volumetric Flow Calculations. For example : if we had a venturi tube generating a differential pressure of 2.30 kilopascals (kPa) at a mass flow rate of 500 kilograms per minute of naphtha (a petroleum product having a density of 0.665 kilograms per liter), we could solve for the k value of this venturi tube as such:

WebThe measured differential pressure differs for each combination and so the coefficient of discharge used in flow calculations depends partly on the tapping positions. The simplest installations use single tappings upstream and downstream, but in some circumstances these may be unreliable; they might be blocked by solids or gas-bubbles, or the ... WebDifferential pressure transducers have been widely used to measure flow rate of in-compressible liquids such as water. The most common method is to measure the pressure drop across an orifice plate in the pipe and calculate the flow rate. An orifice plate is simply a plate installed in the pipe, usually between flanges, that has a hole of a ...
