THEORY OF ORIFICE MEASUREMENT The law of conservation of energy applied to a fluid under the condition of steady, uniform flow requires the total energy of the system to remain constant. Therefore, the sum of the potential energy, pressure energy, internal energy, and kinetic energy upstream of a constriction must equal the sum of the potential energy, pressure energy, internal energy, and kinetic energy downstream of the constriction, assuming that no heat has been added or lost.
The wide variety of applications available today demands dependable, accurate measurement. Recently, significant improvements in metering standards and secondary equipment have enhanced the overall quality and efficiency of orifice metering. Given the proper design considerations, orifice metering satisfies the measurement requirements for a variety of applications.
