Apex CN1293SDF590N Oil Gauging Tape 50 Ft Steel

Product Description

The APEX CN1293SDF590N is an Atlas Double Duty oil gauging tape designed for measuring fluid levels and ullage in storage tanks. The tape features a 50-foot chrome clad and Nubian finish steel blade in the D2 style, measuring 0.5 inches wide. The 590 bob cut at the weighted end ensures consistent, repeatable contact with tank bottoms. This tool is built for field use by petroleum storage technicians, tank gaugers, and compliance inspectors who need accurate manual tank readings. The chrome clad finish resists corrosion from hydrocarbon exposure, while the Nubian side assists with water detection at the tank bottom.

This gauging tape is used in bulk liquid storage applications including fuel oil, diesel, crude oil, and other petroleum-based fluids stored in vertical or horizontal tanks. It is suited for tank farms, fuel distribution terminals, fleet fuel facilities, and marine bunkering operations. Technicians use this tape for both product-level measurement and water interface detection in a single pass, which is the defining function of the double duty design.

Key Features

• 50-foot steel blade for measuring deep storage tanks in a single drop
• Chrome clad and Nubian dual-finish blade enables simultaneous product level and water interface detection
• D2 blade style with 0.5-inch blade width for standard gauging tape reel compatibility
• 590 bob cut provides stable, repeatable contact on tank floor during measurement
• Steel blade construction resists deformation and maintains calibration accuracy over extended use

Compatibility

Designed as an OEM-style replacement gauging tape for standard oil tank gauging reel assemblies used in petroleum storage and distribution applications.

Installation Notes

Oil gauging tapes are deployed by petroleum measurement technicians following API MPMS standards for manual tank gauging. Before gauging, confirm the tank is not under pressure and that vapor conditions are safe for open-gauge work. Lower the tape steadily to avoid kinking the blade, and allow the bob to settle fully before reading. Never use this tape in tanks where the fluid is incompatible with steel or chrome-finished blades.
