适用范围：This European Prestandard describes the methods and accuracy of measurement for temperature, pressure, fluid quality and massflow of different fluids and how to determine the pressure drops across a heat exchanger.Measurements are restricted to those necessary for establishing the performance of heat exchangers classified in ENV 247 using the fluids listed in ENV 247.This European Prestandard applies when referenced by the various branch application standards. The specific application European (Pre)standards shall be the prime reference doucments.
