WebPartial-insertion averaging pitot tubes Partial-insertion flowmeter pitot tubes are a shortened version of the full-insertion tube and typically span only approximately 1/ 3 to 1/ 2 of the full stack diameter. The number of velocity sensing holes is reduced to take only an average velocity across that portion of the stack diameter. WebIts operation is simple: in order to pass through the tapered tube, the fluid flow raises the float. The greater the flow, the higher the float is lifted. In liquid service, the float rises due to a combination of the buoyancy of the liquid and the velocity head of the fluid.
