Abstract: Coriolis flow meter is widely used to measure the mass flow rate in many fields of research and industry because of its highly accurate measurement performance and superbly repeatable characteristic . The working principle of Coriolis flowmeter relies on the Coriolis Effect generated by the fluid flowing through the v ibrating tubes. Therefore, the measurement accuracy of a Coriolis flow meter might be influenced by the vibration surrounding a Coriolis flow meter , the flow pulsation, and the fluid distribution between the vibration tubes . The presented work studies the impact s of possible vibration , and asymmetric flow pattern induce d by the water flow ing through a partially closed ball valve on a Coriolis flow meter . W hen a partially closed ball valve and the Coriolis flow meter are installed in series , the vibration caused by the water flow hitting a partially closed ball valve would result in a clear measurement error and a negative effect on the short - term repeata bility of the Coriolis flow meter is observed . The installation of two rubber sections surrounding the C oriolis flow meter is effective to isolate the vibration as a n oise on the measurement result. A
