MMC D-2401-2 Tri-mode gauge, Gastight type, Made in USA

The MMC D-2401-2 oil gauge, airtight, sx type in the USA is a fully airtight type, using an electronic controller with battery power. When inserting the ruler into the blocking valve on the measuring tube of the cargo tanks, it forms a completely closed system, which prevents the toxic vapor of the goods from escaping from the tank and creates a closed-type measuring system for that container.

The unit of measurement on the ruler wire is shown in a meter or inch system and is coated with anti-interference layer (sensor signal). In addition, the ruler is marked with color to show the direction of rotation, making it easy to observe when the ruler moves to the receiving position completely. The ruler is equipped with a cool cord with a large clamping head. This measuring device is widely recognized in the world, equivalent to a fixed installation measuring system because the ruler can remain in place connected to the valve on the measuring tube of the tank from the beginning until the end of the pump receiving or returning.

EN: FLEXI-DIP Closed Trimode Gauging Tape

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 clips 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.
