Abstract
A flowmeter for determining the amount of flowing medium using an orifice (4) and a resistor body (5) in a cavity (6) through which the medium to be measured flows. Not the resistor body (5) but an orifice sleeve (4) is displaced as a consequence of the varying primary pressure and thus the degree of opening of the flow orifice is determined depending on the amount of flow of the flowing medium. A satisfactory linearization of the subregion of the function .DELTA.p (V) is obtained.
