WebOrifice plate flowmeters. The orifice plate is one in a group known as head loss devices or differential pressure flowmeters. In simple terms the pipeline fluid is passed through a restriction, and the pressure differential is measured across that restriction. Based on the work of Daniel Bernoulli in 1738 (see Module 4.2), WebThe orifice velocity head loss coefficient and orifice flow area are calculated for information during each iteration. The calculation routine is described in the following steps: 1. Calculate Reynolds number 2. Estimate Beta ratio 3. Estimate flow coefficient using Beta ratio estimate 4. Estimate orifice velocity head loss coefficient 5.
