Abstract
A rotary type flowmeter having a variable orifice through which the flow to be measured is directed toward a rotatable needle. A preload is also applied and which may be varied as desired. By the use of the variable orifice and with the preload, the same flowmeter may be used for differing ranges of flow by minor adjustment and various indicating scales may be taylored to the particular flow being monitored.
