Abstract：The effects of different installation conditions on measuring accuracy of ultrasonic flowmeter were studied by means of experimental test and numerical simulation. The experimental results show that the rusted straight pipe section and whether or not to install flow conditioner and which flow conditioner to install have a great influence on the flow state and measurement results. The numerical simulation results support the experimental results. In order to ensure the accuracy and reliability of the trade handover, the verification and on-site use and installation should meet the standard requirements. If the consistency cannot be achieved, it is suggested to submit the supporting accessories of the flow meter for inspection together.
