The APEX CN1294SF590N is an Atlas Double Duty oil gauging tape designed for accurate measurement of liquid levels and depth in storage tanks and fuel oil systems. The blade features a Chrome Clad/Nubian finish on a D1-style steel blade that delivers durability in demanding field conditions. At 66 feet in length and 0.5 inches wide, this tape provides sufficient range for standard above-ground and underground tank gauging applications. It ships as a single unit and is a standard tool in the inventory of petroleum service technicians, facility maintenance crews, and fuel system professionals.
This oil gauging tape is suited for petroleum storage tank measurement tasks in commercial fueling, industrial, and utility settings. The double-duty blade design allows gauging in both innage and ullage modes, making it versatile across different tank configurations. The 590 bob cut designation indicates the style of the plumb bob fitting used with this tape, which is relevant when selecting compatible bob weights for specific gauging procedures.
Designed as an OEM-style replacement or direct-use oil gauging tape for petroleum storage tank measurement applications where a 66-foot, D1-style double-duty tape with a 590 bob cut is specified.
Oil gauging tapes are deployed by petroleum service technicians following API and applicable facility safety protocols. Before gauging, verify the tank is not under pressure and that the measurement port is safe to open per site-specific procedures. The bob weight must be matched to the 590 bob cut designation before use. Handle the tape carefully during retrieval to avoid kinking the steel blade, which can affect measurement accuracy.
