Abstract
The invention is a flow meter comprising a magnetic field-dependent resistor arrangement whose resistances are controlled by a particularly configured control member. More specifically, the position of the control member controls the degree of flux passing from the permanent magnet of the resistor arrangement through the two magnetic field dependent resistors of the arrangement. The resistance values of the resistors thus vary as a function of the position of a control member. According to the invention, the control member comprises a throttle plate having one end clamped elastically to the flow chamber of the meter and the other end within and free to move with the medium flowing in the chamber. In this manner, by varying the pressure head of the flowing medium, the amplitude of motion of the throttle plate, and, hence, the resistance values controlled thereby are varied. A sensitive flow meter having a simple construction is thus realized.
