Rotating vane type flow meter has been widely used to measure the tap water quantity to each household through water supply network. This device consists of vane rotor and is set across the water piping. The rotor rotation is supposed to be proportional to the total flow quantity. Since this is a measuring device, it must be reliably accurate for defined usage condition, which is usually very strict and wide. In order to design such device, knowledge on the flow condition in them is essential, and since the flow conditions are very complicated, theoretical or computational fluid dynamic analyses are hardly competent. Here we used Hydrogen Bubble Flow Visualization technique, and recorded the various images from the static or rotating systems. We analyzed these images using PIV method and obtained the complete understanding of the flow character in such device.
