Abstract
A flush fluid flow control apparatus having an adjustable flow control valve and a flow measuring orifice combined in a block assembly. The flow control orifice is formed in a tube having a plurality of radial orifices and which can be axially turned to register with the flow channel for selecting flow ranges measurable by the orifice selected. Differential pressure is read across the orifice and communicated to act on a double headed piston which moves through the block proportionally to the differential pressure, the double headed piston compressing air in a chamber to an extent proportional with its movement, and a pressure gauge is installed into the chamber to correlate the movement of the double headed piston with the actual flow rate.
