A mechanism inserted into a liquid flow fine that measures volumetric flow rate and total flow. The meter is constructed with vanes on a spindle inside a housing that can be flanged into a flow fine. The movement of liquid through the meter exerts a force on the curved vanes, causing the spindle to turn, as on a water wheel. The spindle is connected to a counter and readout mechanism, showing rate of flow and total daily or monthly throughput.
