A material metering device having a discrete flow rate adjustment and indicator mechanism. The indicator includes an actuator knob which is rotated to adjust the flow rate of material from the meter. The actuator knob is also operably connected to a follower wheel which is rotated by movement of the actuator knob. Indicia on both the actuator knob and follower wheel are simultaneously registerable with a reference point, such as a viewing window, and the reading of the indicia at the reference point indicates the flow rate of material from the meter. |
