Sprinkler System Gauges
U.S. Gauge P-1590K and R-1590K sprinkler gauges are designed for use on wet or dry sprinkler systems. These 3-1/2" gauges are approved by the Factory Mutual System and are listed by Underwriters’ Laboratories. The R-1590K retarded air gauge is used on the sprinkler head side of the control valve in a dry system to accurately monitor line air pressure and also have the ability to accept water pressure up to 250 psi upon system activation. The P-1590K is used on the water supply side of the system to indicate available source pressure and is used alone on wet systems where water is available to the sprinkler head at all times.
