ABSTRACT:
A gauge for measuring the pressure of a shower or water spray used in a papermaking machine. The gauge includes a body and an arm extends laterally outward from one end of the body and is adapted to be supported on a water conduit or pipe that contains a shower of nozzles. An alignment plate is mounted on the body and has an opening to receive the liquid stream being discharged from the nozzle. A pressure sensing device is located on the opposite side of the alignment plate, and the liquid stream passing through the opening in the alignment plate will strike the pressure sensing device to generate an electrical signal in proportion to the pressure. The electrical signal is then transformed into a measurement of pressure in psi which is displayed on a readout or gauge mounted on the body. The arm can be adjustably connected to the body to thereby adjust the spacing between the nozzle and the pressure sensor, depending upon the diameter of the water conduit.
