Effects Of Abnormal Conditions On Orifice Measurement Accuracy

摘要

One of the oldest types of fluid measurement is based on the concept of forcing a pressure drop and velocity change with a specifically designed obstruction, and measuring die pressure change on either side of the obstruction, then applying these readings to a formula to calculate the fluid flow. This obstruction is called an orifice plate and die overall process is called orifice measurement. Orifice measurement includes an orifice, a meter tube, and sensing equipment.
