Rethinking Dry Calibration
Abstract
The use of dry calibration for modern flowmeter technologies may offer a way to reduce the frequency and cost of wet calibrations. This paper contrasts the acceptability of dry calibration for the orifice plate with the use of dry calibration for modern flowmeters. Some background to dry calibration is reviewed, in particular for the electromagnetic flowmeter (EMFM). Suggestions have been made to achieve dry calibration in modern flowmeters, and the paper explores how this might be achieved in various designs. Some new strategies are discussed for dry and in-situ calibration. It is concluded that dry calibration techniques should be reconsidered and incorporated within the design and manufacture of meters, and combined with e-calibration.
