A short note on the speed calibration of the Geodyne model 920 current meter [electronic resource] / H.S. Weiler. Ottawa : Inland Waters Branch, Dept. of the Environment, 1971. v, 7 p. : charts. Technical bulletin ; no. 57 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "The Geodyne Division of EG&G International manufactures the Model 920 Tape Recording Current Meter. With the meter, it supplies a standard speed-calibration table. Comparison of this table with direct calibrations shows that the standard table produces large errors in the measurements, especially at low speed, Analysis of these errors leads to the conclusion that the standard table should not be used; rather, a table formed from fitting least-square curves to direct calibration data would give much greater accuracy in speed measurements"--Abstract, p. v.
