Paperback. Condición: New. Print on Demand. This book presents a detailed analysis of a steam flow meter extensively tested by the author. These tests sought to determine the accuracy of the meter and consistency of its readings. The author carefully describes the construction, set-up, principles, and operation of the meter befo…re delineating the test procedures and extracting the data. They present three main observations from the data. First, though the meter's readings generally align with the actual flow, they tend to underestimate the flow rate, requiring calibration to improve accuracy. Second, errors in the readings are not connected to the quality or pressure at which the meter is utilized. Third, because the meter lacks precision and is not well-suited to calibration, it is of limited value for efficiency tests or boiler tests. In the end, the author concludes that while the meter could be valuable as an aid for testing efficiency or boilers if it were more accurate or could be accurately calibrated, the model tested is not. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
