ABSTRACT:
A flow meter having a float slideably mounted along a float rod centrally located within a flow meter body, the float assuming a height along the flow meter float rod representative of fluid pressure. The float preferably has a cylindrical-shaped through-bore. The float rod preferably has a polygonal-shaped perimeter over substantially its entire length permitting fluid flow between the float rod outer diameter (OD) and the float inner diameter (ID) to dislodge any particulate, thereby serving a self-cleaning function. The float rod is preferably hollow and closed at its upper end and having flow inlet and flow outlet openings near its lower end communicating with a flow chamber which conveniently provides the inlet and outlet flows at the lower end of the flow meter.
