Abstract:
A bidirectional sphere prover is used to check the accuracy of a custody transfer meter when fluids, such as crude oil or gasoline are bought and sold. The bidirectional sphere prover of the present invention uses a straight calibrated section of pipe between the detection switches, the straight calibrated section of pipe being free of welds, flanges and elbows.
