Closed Gas Tight Trimode (UTI) Gauging Tape

Enhanced ‘CLOSED Gauging Systems

In a move to address the special needs of chemical and refined product carriers and barges, MMC International Corp. has announced the release of a new “closed” gauging system design.

Featuring an ullage range of 15-30 meters, the system uses a new “PeeK” plastic sensor suitable for most chemical products and also refined petroleum products.

Surface Mount Technology
The sensor employs state-of-the-art SMT (Surface Mount Technology) and circuit enhancements that provide better long term reliability, more precise ullage level sensing, and improved oil-water “layer detection.”

The new compact model retains the same trouble-free, gas-tight, heavy duty mechanical design as its larger VLCC class brother. Both models now have built-in viewing window wipers.

“Intrinsically Safe”
All models are also approved as “Intrinsically Safe” (Exia IIC T4) and as Class 1, Div. 1 gas groups’ C&D equipment.

Equipment quality is assured by SIRA (Baseefa) annual audits to confirm that quality requirements of ISO 9001 are maintained in addition to their supplementary requirements.

Periodic safety compliance audits are also conducted by CSA, SIRA (ATEX), BV, DNV, CSS.

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.
