A liquid flow meter is disclosed including a compartment enclosure formed from an upper case part and a lower case part, the lower case part containing a volumetric measuring container having a specified fluid volume capacity, mounted upon a rotatable pivot having an axis of rotation and having a counterbalance weight. The axis of rotation of the volumetric measuring container being determined by location of said rotatable pivot. The moment created by the counterbalance weight about the axis of rotation maintains the static filling rotational position until the specified volume capacity is achieved. An influent port is formed in the upper case part for directing liquid flow approximately vertically into the approximate center of said volumetric measuring container. The lower case part has a sloped bottom and flumage to receive flow discharge of the volumetric measuring container and directs the liquid volume to an effluent port.
