Abstract
An apparatus for reducing or diffusing the pressure within a high pressure stream of water or other fluid and simultaneously measuring the pressure in the flowing stream includes an inlet pipe fixed to a perpendicular discharge pipe to form a T-joint having two discharge ends covered with metal screen. A flow splitter is mounted transversely along a diameter of the inlet pipe for splitting the turbulent incoming fluid flow into two laminar flow sheets. A Pitot tube or probe is seated in the center of the flow splitter and is connected to an external pressure gauge by a Pitot tube static line comprising a bore through the flow splitter. The flow splitter includes a wedge splitter portion having substantially a triangular cross section and presenting the apex or narrow edge of the wedge to the incoming fluid flow.
