Abstract
A connector and gauge assembly for measuring liquid pressure and flow rate has an axially elongated integral tubular body with an externally threaded male end and an opposite female end. The tubular body defines an axial main conduit, and a test conduit generally transverse thereto. An internally threaded sleeve is rotatably mounted upon the body at the female end for connection of the main conduit to a source of liquid under pressure. A closure element is associated with the tubular body for resisting flow of liquid through the main conduit. A gauge of pressure and flow rate is mounted upon the tubular body in communication with the test conduit, the gauge having a display for indicating pressure and flow rate.
Claims5
A gauge and connector assembly for measuring liquid pressure and flow rate, comprising:
- an axially elongated, integral tubular body having an externally threaded male end portion and an opposite female end portion, said integral tubular body defining an axial main conduit, and a test conduit generally transverse to said main conduit;
- an internally threaded sleeve rotatably mounted upon said integral tubular body at said female end portion and adapted for connection of said main conduit to a source of liquid under pressure;
- a closure element associated with said integral body for resisting flow of liquid through said main conduit;
- and
- a gauge of pressure and flow rate mounted upon said integral tubular body and in communication with said test conduit, said gauge comprising a pointer, a first display surface for indication of liquid pressure, and a second display surface for indication of liquid flow rate, said first display surface and said second surface display being mutually adjustable.
A method for determining liquid line pressure and flow rate in a line of hosing having an externally threaded male outlet and an opposed internally threaded female inlet, the method comprising the steps of:
- providing a connector and gauge assembly for measuring liquid pressure and flow rate comprising an axially elongated integral tubular body having an externally threaded male end portion and an opposite female end portion, said integral tubular body defining an axial main conduit, and a test conduit generally transverse to said main conduit, an internally threaded sleeve rotatably mounted upon said integral tubular body at said female end portion and adapted for connection of said main conduit to a source of liquid under pressure via the spigot;
- a closure element associated with said integral body for resisting flow of liquid through said main conduit;
- and a gauge of liquid pressure and flow rate mounted upon said integral tubular body and in communication with said test conduit, said gauge comprising a pointer, a first display for indicating liquid pressure and a second display for indicating liquid flow rate, said first display surface and said second surface display being mutually adjustable, said main conduit having a predetermined cross-sectional area and said display of said gauge being calibrated for simultaneous indication of pressure and flow rate;
- engaging the internally threaded sleeve of the tubular body with the externally threaded male outlet of the hosing to connect the main conduit to the source of liquid under pressure;
- engaging the externally threaded male end portion of the tubular body with the internally threaded female inlet of the hosing;
- adjusting said closure element to allow flow of liquid through said main conduit;
- actuating the flow of liquid through the hosing;
- and
- observing the indications of liquid pressure and liquid flow rate displayed upon the first and second displays of said gauge.
