MMC Vapor Control Valves, Cam-Lock Flanges
and Product Measurement & Sampling Instruments

MMC International Corporation manufactures vapor control valves, quick coupling flanges, product sampling equipment, and product measurement instruments which meet or exceed the standards for "intrinsically safe" equipment set by governments and certifying agencies around the world.

MMC's primary products include Cam-Lock flanges, vapor control valves, deck covers, oil-water separators, cargo UTI measurement devices, high level alarm systems, gas samplers, product samplers and related items for the maritime petroleum and chemical transport industry as well as land-based petro-chemical facilities. One of the oldest and most experienced firms of its kind, MMC is widely acknowledged for its history of technological innovation and the dependability of its products.

Portable Electronic Gauging Tapes for Petroleum and Chemical Tanks

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, BASEEFA, CSA and SAA.

UI Oil-Water Interface Gauging Tapes For Tankers, Shore Terminals and Environmental Applications

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's UI gauging tapes are capable of detecting all floating and non-conductive hydrocarbons.

Each instrument is designed for ease of use. Gauging for liquid or Interface level is accomplished simply and quickly. When the electronic probe is lowered and senses a hydrocarbon, a steady horn tone is sounded and a yellow LED illuminates. When sensing an Oil-water interface, or a heavier than water non-conductive liquid, an intermittent horn tone sounds and a red LED begins flashing.

This gauging system is certified as "Intrinsically Safe" for use in all class IIB hazardous atmospheres.
