STANDARD VOLUME PIPE (PIPE PROVER)
These are standard volumetric pipes to calibrate flowmeters (PD flowmeters such as oval-gear and UF-II meters and turbine meters) for accuracy on-line. Six models of bi-directional prover (reference volume: 0.2 to 10m3; reference max. flowrate: 40 to 2,200m3/h), and seven models of 3-sphere type prover (reference volume: 0.5 to 20m3; reference max. flowrate: 5 to 4,000m3/h) are available.
