Measurement of circulating water flow rate can provide indications of cooling system problems and can be used to calculate turbine cycle heat rate. Unfortunately, this parameter is often difficult to accurately measure in power plants. A particular problem arises when a circulating water system cannot provide the necessary location and conditions (i.e., fully-developed flow profile) for the use of conventional measurement technology that are essential for obtaining highly accurate results. A low drag insertion turbine flow measurement system can overcome this problem because it is not dependent upon a fully-developed flow profile to obtain highly accurate results. This paper describes the applications and results of performing circulating water flow measurement using a high accuracy low drag insertion flow metering system in locations without a fully-developed flow profile. A case study of this type of measurement at Dairyland Power Cooperative`s Genoa Station is presented and compared with the results of a dedicated magnetic influent flowmeter measuring flow in a large cross-section of a round tunnel more than one quarter of a mile straight where fully-developed flow is present. The results indicate a close agreement ({approx}{plus_minus}2% from each other).
