摘要： A measuring apparatus is disclosed which is operated by the flowing of a medium. The apparatus comprises a rotor fitted coaxially within a flow pipe, a tachometer of the rotor and a flow guide member comprising a director and a controller. By means of these members the flow can be divided, according to the message received from a sensing element, into two components, of which at least one is screw-shaped or spiralling. By employing such a guide member the rotor is easily started, and its rotating speed is directly comparable to the quantity to be measured, as well as to volume flow. The sensing element can be for example a spiral-shaped bimetallic member reacting to changes in the flow temperature, the member being attached at its one end to the flow pipe and at its other end to the director. According to changes in the temperature the sensing element revolves around the director with respect to the controller, and the mutual proportion of the flow components is changed, as well as the rotating speed of the rotor.
