MMC is the world's leading manufacturer of portable instruments for measuring ullage, oil-water interface, temperature, and bottom dryness in shipboard and land-based petroleum and chemical tank systems.
All MMC systems are manufactured in the United States and are certified as intrinsically safe by Factory Mutual, SIRA/BASEEFA and CSA.
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 or english 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.
