MMC is a global leader in manufacturing Portable Electronic Gauging Tapes designed for accurate tank measurement in shipboard, refinery, terminal, and land-based petroleum or chemical storage tanks. Engineered with advanced electronic gauging technology and built to meet strict international safety standards, MMC gauging tapes ensure precise, reliable, and leak-free liquid level measurement even in hazardous environments. These portable gauging systems are widely used in the marine, oil & gas, and petrochemical industries for safe tank inspection, inventory control, and efficient cargo monitoring, making MMC a trusted choice for high-accuracy tank gauging and secure tank measurement operations.
The MMC Closed Type Sampler – Flexi-Dip is an advanced closed tank gauging and sampling system designed for safe and accurate measurement on chemical carriers, product tankers, and petroleum vessels. Engineered with MMC’s high-performance PEEK plastic sensor and advanced Surface Mount Technology (SMT), this system delivers precise ullage measurement, oil–water interface detection, and temperature monitoring while maintaining complete vapor-tight operation. Its closed sampling design prevents vapor release and cargo contamination, making it an ideal solution for hazardous cargo handling in marine, oil & gas, and petrochemical applications, ensuring safe, reliable, and efficient tank gauging operations.
The Closed Flexi-Dip™ UTI Meter is a battery-powered, intrinsically safe tank gauging device designed for accurate measurement through vapor control valves on cargo and storage tanks. This advanced closed-system UTI meter enables precise ullage, temperature, and interface measurements while preventing the release of hazardous vapors during cargo handling operations. Featuring an anti-static coated tape and sensor and available in both metric and imperial units, the Flexi-Dip™ ensures safe, reliable, and compliant tank gauging for marine vessels, oil & gas facilities, and industrial storage tanks, making it an ideal solution for operations in hazardous and regulated environments.
The Flexi-Dip Sampling Tape (Restricted Gauging) is an advanced closed gauging and sampling solution developed by MMC for safe and precise measurement of bulk petroleum and chemical products. Designed to support restricted tank gauging operations, this system ensures accurate sampling while minimizing vapor exposure and maintaining cargo safety. Built with MMC’s commitment to operator safety, durability, and ease of use, the Flexi-Dip Sampling Tape delivers reliable and efficient tank measurement for marine vessels, oil & gas facilities, and industrial storage tanks, even in demanding and hazardous operating environments.
MMC International USA Vapor Valve
The MMC International USA Vapor Valve is an essential component of closed tank gauging systems used on tankers carrying petroleum and chemical cargoes. Installed on the tank top, this vapor control valve allows safe and compliant measurement of ullage, temperature, oil–water interface, bottom dryness, oxygen levels, and liquid cargo sampling using portable gauging instruments. Designed to maintain a vapor-tight seal, it prevents the release of hazardous gases during cargo operations, ensuring safe tank gauging, improved crew protection, and regulatory compliance. Widely used in the marine, oil & gas, and petrochemical industries, the MMC Vapor Valve provides a reliable solution for accurate closed-system tank measurement and safe cargo monitoring on tankers.
