PROVER FOR CALIBRATING A FLOW METER WITH IMPROVED ACCURACY

摘要

PURPOSE: A prover for calibrating a flow meter is provided to be used even if parts of detectors are out of order and to simultaneously measure various flow meters. ;CONSTITUTION: A prover for calibrating a flow meter comprises a prover pipe(10), a four-way valve(18), and a forcer(20). The prover pipe has a reference volume. The four-way valve generates a fluid flow. The forcer fixes a flow meter(22) based on the volume of fluid exhausted from the prover pipe. The proper pipe comprises four detectors(D1,D2,D3,D4).;COPYRIGHT KIPO 2011
