- Abstract:
- One way to validate the volume measurement of the piston prover cylinder is using gravimetric method called water draw. The purpose of this study is to measure the volume of piston prover cylinder with gravimetric method for validation of its water flow rate measurement value and also to achieve the uncertainty target. The measurement results of piston prover cylinder volume are 92.43 litre and expanded uncertainty of 0.09 litre or 0.09% in relative. The largest contribution comes from the water mass measurement repeatability because of the possibility of evaporation and error measurement in using three-way valve as diverter. The Data collecting methods should be improved in the future.
