Inside Diameter Measurements for the Cylinder of a 20 L Piston Prover

Abstract
We made inside diameter measurements of a stainless steel cylinder used in a piston prover for hydrocarbon liquid flow measurements. We used a 3-point micrometer and two traceable setting rings to measure diameter at 12 radial positions at each of 21 lengthwise positions, on three different occasions. The diameter measurements showed a change in diameter of about 20 m near the middle of the cylinder and non-circularity at one end. These shape imperfections lead to a diameter uncertainty of 6 m (k=2) for the cylinder in its present form. The cylinder will be re-honed and chrome plated to improve the uniformity of diameter along the length and increase the surface hardness (to prevent scratches). Based on the measurements presented herein, diameter uncertainty of 2 m or less appear attainable by this measurement approach.Proceedings Title
