Scully Signal 1422 Swing Arm Tank Level Gauge

Product Description

The SCULLY SIGNAL 1422 is a swing arm liquid level gauge designed for accurate tank level monitoring in fuel storage applications. Known commercially as the Econ-O-Gauge, this mechanical indicator fits tanks with a depth of 42 to 44 inches and accepts either a 1-1/2 inch or 2 inch tank opening. The gauge uses a non-corrosive swing arm mechanism to translate liquid level into a readable position indicator, providing dependable readings without electrical power or sensors. It is installed by fuel oil service contractors and equipment technicians on residential and commercial aboveground storage tanks.

The 1422 is suited for aboveground fuel oil storage tanks found in residential heating systems and light commercial fuel supply setups. The gauge mounts into a standard threaded tank opening, making it compatible with common tank fitting configurations. Its mechanical design requires no wiring or calibration tools, and it is well-suited for retrofitting existing tanks where a visual level indicator is needed. Contractors and service technicians use it as a direct replacement for worn or failed swing arm gauges on tanks in the 42 to 44 inch depth range.

Installation Notes

Installation is performed by licensed fuel oil service technicians or qualified contractors. Before servicing the tank fitting, depressurize and isolate the tank according to local fire and safety codes. Thread the gauge body into the tank opening using appropriate pipe thread sealant rated for petroleum service. Do not overtighten the fitting, and verify the swing arm moves freely through its full range before returning the tank to service.
