MONITORING THE REPEATABILITY AND REPRODUCIBILITY OF A NATURAL GAS CALIBRATION FACILITY

Thomas Kegel, William Johansen

Abstract

The high flow system of the Iowa natural gas facility has been in place for 14 years. A number of programs are maintained to monitor the random effects. Traditional control chart techniques have been adapted for the measurements of pressure, temperature, gas composition and flowrate. Turbine meter calibration standards have traditionally been monitored using ultrasonic check meters. A new low flow system has recently been installed that makes use of ultrasonic meters as both calibration and check meters. This paper will describe the development and interpretation of some monitoring techniques for the various flowrate standards.
