ABSTRACT:
A fluid flow meter is provided and comprises a tubular and cylindrical housing constructed of a transparent material and having an upper axial end, a lower axial end and defining an interior fluid chamber therebetween. A fluid inlet is fluidly connected to the lower end of the chamber while a fluid outlet is fluidly connected to the upper end of the chamber. At least one and preferably several flow responsive members are disposed and freely moveable within the interior of the fluid chamber. The members have a density greater than the density of the fluid flowing through the flow meter but are vertically displaceable within the interior chamber in an amount proportional to the fluid flow rate through the flow meter. The density and surface area of the members can be varied as desired in order to provide for different flow rates and flow ranges. In addition, in the preferred form of the invention, a magnetically operated switch is adjustably connected to the housing and is actuated by the presence of a flow responsive member at a predetermined vertical level within the fluid chamber and is thus representative of a predetermined flow rate.
