MMC Triple Function Tape CLOSED (chem) for measuring ullage, temperature & interface.

These portable FLEXI-DIP® “UI” gauging tapes provide a convenient and accurate means for measuring ullage and a lower oil-water interface. They are suitable for marine and land-based tank facilities and also for environmental monitoring well applications.

MMC Triple Function Tape CLOSED (chem)

The Portable Closed Flexi-Dip measuring tape is a battery-operated electronic unit that is totally gas-tight. When installed in a vapor-control valve mounted on a storage (cargo) tank, it forms a tightly sealed system that prevents toxic vapors from escaping and creates a closed gauging system for that tank. The tape is marked in metric scale units and is anti-static coated (as is the sensor). In addition, the tape is color marked to make tape direction and motion easily seen and to ensure full rewind position. A coiled grounding cable with large alligator clip is standard. This closed system is recognized by many worldwide regulatory bodies as equivalent to a fixed gauging system as long as the tape remains in the valve from the beginning until the end of loading or discharging of the tank.
