摘要
A flow meter prover (120, 220, 320) is provided with multiple pairs of detectors to record multiple calibrated prover volumes with a single pass of the displacer 124. The prover conduit 122 may be fitted with a first pair of detectors (116, 118) for a first calibrated prover volume (V1) and a second pair of detectors (130, 132) for a second calibrated prover volume (V2). A single pass of the displacer may trip more pairs of detectors (216, 218, 230, 232, 234, 236) corresponding to more calibrated prover volumes (V3, V4, V5). A flow computer 326 may be configured to record more than two calibrated prover volumes (V6, V7, V8, V9) using only two pairs of detectors (316, 318, 330, 332) and a displacer (324).
