97-05: Accuracy and Linearity of Diamond Shaped Averaging Pilot TubesWater flow measurement is a critical factor in the acceptance testing of cooling towers. As described in previous technical papers, measurement using pitot tubes another velocity type probes is controversial. This paper describes the consistency and accuracy of using a diamond shaped averaging pitot tube technology for acceptance testing in water flow measurement. The paper is based on data collected at an actual cooling tower test, testing at a major
