A flow meter is provided using a fluid responsive solid member which is introduced into a flow chamber defined in a vertically standing tubular housing and which, with the flowing fluid supplied through an inlet at the lower end of the housing and discharged through an outlet at the upper end of the housing, is propelled to a level as a function of the volume rate of flow of the fluid within the chamber. The solid member is composed at least in part of an electromagnetically susceptible material and an electrically conductive winding is disposed in an electromagnetically inductive relationship with that member to present a reactance which varies as a function of the position of the member in the flow chamber.
