MMC is a global leader in manufacturing Portable Electronic Gauging Tapes designed for shipboard, refinery, terminal, and land-based petroleum or chemical storage tanks. Built with cutting-edge technology and strict safety standards, MMC’s gauging tapes deliver accurate, safe, and leak-free tank measurement even in hazardous environments.
Intrinsically Safe, Closed Tank Gauging
MMC’s flagship models — including the Portable Closed Flexi-Dip system — are battery-operated and fully intrinsically safe, preventing ignition in flammable environments. These units create a sealed, vapor-tight gauging system, ensuring no toxic vapors escape during ullage, temperature, interface, or bottom dryness measurements.
Certified by BASEEFA and CSA, MMC gauging tapes are widely accepted as equivalent to fixed tank gauging systems when properly installed during tank loading or discharge operations.
