Description

The Bell Piston Prover BPP10 is a primary standard for flow calibration with air and other gases (natural gas) at operating pressure up to 6 bar. The piston

is moved via an electrical motor: In the initial state the piston is fully retracted (upper position). At the end of a calibration procedure the bell is fully extended (lower position). Using the dimensions and the travel speed of the

piston the flow is determined exactly. The measuring time is greater than 20 seconds.
