DOUBLE PISTON PROVER USABLE AS FLOWRATE COMPARATOR FOR VARIOUS GASES

• Abstract:

  For the calibration of small flowrates and for use with different gases, a novel double piston prover with a spindle-stepper motor drive has been developed. The piston prover allows flowrates being generated with a very good reproducibility and flowrate constancy, and it therefore also makes possible the calibration of meters under test which generate a constant flowrate like critical nozzles. By means of this principle, it was possible to realize for the first time a flowrate comparator which can also be used for the measuring of gas flows.
