|dc.description.abstract||This paper reports on the efforts to calibrate flow sensors that are being used to monitor building thermal energy use in a large scale monitoring project. Several insertion-type paddlewheel meters are being tested with a dynamic-weight flowloop at varying flow velocities in pipe sizes ranging from 3-12 inches to establish their accuracy and metering characteristics. Preliminary tests indicate that some of the meters do not have the correct multiplying factor and as a result, indicate flow rates that are as much as 15% lower than the actual flow rates. However, when a corrected multiplier is applied the meters perform to within ±5% of the flow rate. Preliminary tests also show that magnetic type paddlewheel meters may not be the best choice for flow rates below 2 ft/s.||en|
