Btu Meter Technology Review. Purchase This Document Btu Meter Technology Review. This study was performed to evaluate the technology status of available Btu meters that can be used for individual metering in multifamily buildings. Calibration studies were performed on 16 used and seven new Btu meters, and six experimental Btu meter integrators being developed by another GRI contractor.
Results show that the main source of error is in the flow meter component.
All of the flow meters and Btu meters exhibited errors in excess of the manufacturers' published values. The flow meters occasionally showed poor repeatability, and accuracy was affected by water temperature. Commercially available signal processors tested with precisely simulated flow and temperature input signals exhibited errors in Btu readings exceeding plus or minus three percent. Developmental signal processors achieved an accuracy of plus or minus two percent. You must be a registered user to purchase this document.
