The importance of flow measurement in the industry has grown in the past 50 year, not just because it was widespread use for accounting purposes, such as custody transfer of fluid from supplier to customers, but also because of its application in manufacturing processes [1,2, and 3], Examples of the industrial involvement in flow measurement includes food and beverage, oil and gas industry, medical, petrochemical, power generation and water distribution, etc. In the research laboratory, advanced flow measurements are providing new insights into a wide range of engineering flow problems in hydrodynamics such as wave impact loading on coastal defenses, beach erosion) combustion such as low Nox burners in IC engines, aerodynamics such as wind turbine optimization and performance prediction) to list but a few [4,5], The aim of this work is to generate an awareness and understanding of the range of contemporary flow measurement techniques available with the emphasis on devices and techniques with wide application in engineering. Focus is devoted to cheap meters with reasonable accuracy; the differential pressure flow meters that all infer the flow rate from a pressure drop across a restriction in the pipe. An orifice plate meter is designed to measure the required flow rate to cool a nuclear reactor at design point is 20 Kg/sec. Meter operation at off design conditions; 5 and 30 Kg/sec minimum and maximum flow rates with maximum allowable orifice pressure drop of 200 KPa were investigated and finalizes the design process.
