Abstract:
A flow meter prover () is provided with multiple pairs of detectors to record multiple calibrated prover volumes with a single pass of the displacer . The prover conduit may be fitted with a first pair of detectors () for a first calibrated prover volume (V) and a second pair of detectors () for a second calibrated prover volume (V). A single pass of the displacer may trip more pairs of detectors () corresponding to more calibrated prover volumes (V, V, V). A flow computer may be configured to record more than two calibrated prover volumes (V, V, V, V) using only two pairs of detectors () and a displacer ().
