MMC Closed Type Sampler Flexi-Dip
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 15-35 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” 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.

Sampler Tape Model “C” Style
- Fixed-In-Place (FIP)
- Portable-In-Place (PIP)
- Both Flexi-Dip systems
Fixed-in-place And Portable Systems
MMC’s Flexi-Dip Tank Sampling System is available in two varieties: the Fixed-In-Place (FIP) version designed for use with MMC’s unique S series vapor control valves with built-in sampling ports, and the Portable-In-Place (PIP) version designed for use with any standard MMC vapor control valve. Both Flexi-Dip systems are made entirely in the USA by MMC.
Fixed-In-Place (FIP) Version
The Flexi-Dip Fixed-In-Place (FIP) sampling system, valve, and “closed” sampling tape is a unique MMC Model MBS Fixed-In-Place vapor-control valve with a built-in sampling port. The S series of valves, including the BS and MBS, are simple to install, easy to maintain, and convenient to use. The valves and Flex-Dip FIP system will support the collection of 1/2- and 1/3-liter samples. (2″ Model MBS and BS valves for 1/2-liter sampler).
The FIP system, valve, and sampling tape is a gas-tight system. When it is closed and the tape is attached to any S series valve, it can extract and bottle a sample in place without exposing the sample to the atmosphere. The sample bottle twists off easily for capping, labeling, and transportation to the lab. Designed to meet or exceed all existing vapor-control regulations, the system is completely gas-tight. It employs a unique vapor return hose assembly which directs the sample bottle’s vapors back to the tape housing to maintain the system’s gas-tight integrity.
The Flexi-Dip FIP sampling system also includes a sturdy, molded plastic carrying case for convenient transportation and safe storage. Laboratory-grade, unbreakable sampling bottles are also available, along with a convenient sample bottle included with each system.
Portable-In-Place (PIP) Self-Contained Version
The Flexi-Dip Portable-In-Place (PIP) sampling system is designed for use with a wide range of standard MMC vapor-control valves, such as the B and MB units.
In parallel with the FIP version, the PIP sampling system is gas-tight and designed to meet or exceed all existing vapor-control regulations. The system also features a unique vapor return hose assembly which routes the sample bottle’s vapors back to the tape housing to maintain the system’s gas-tight integrity. Laboratory-grade, unbreakable sampling bottles are also available, along with a convenient sample bottle included with each system.
Please note:
- For the FIP system, valves and sampling tapes are ordered separately
- FIP and PIP systems include either a 1/2- or a 1/3-liter zone sampler device
- Closed-sampling gauging tapes are available in standard lengths of 100 feet or 40 meters
Closed Gas Tight Sampler
The MMC Gauging Sampling system is part of a growing family of MMC products designed to make the gauging and sampling of bulk petroleum and chemical products, more accurate and
safer. The easy use and safety in utilization of MMC Product equipment is always foremost in the minds of our designers.
The use of MMC Restricted Gauging and Sampling Equipment, in conjunction with MMC
Vapor Control Valves is well known and established worldwide.
Basic Operating Procedures
This operation requires the use of MMC’s sampler tape and a suitable sampler container.
As far as cargo sampling, the sampler tape barrel is inserted into the vapor valve, and the
securing collar tightened. The vapor valve can now be opened, and the sample container lowered into the product.
A product sample is being taken into the sample cylinder as it is lowered into the desired sample level. Upon obtaining the desired sample level, the cylinder is raised with a continuous motion up into the sampler tape barrel, the valve is then closed.
The sampler tape can now be removed from the station. Carefully lower the sample container from the barrel and disconnect from the sampler hook. The contents of the sample container may now be poured into a suitable transfer container.

Introduction
The MMC Closed Gauging Sampling system is part of a growing family of MMC products designed to make the gauging and sampling of bulk petroleum and chemical products, more accurate and safer.
The easy use and safety in utilization of MMC Product equipment is always foremost in the minds of our designers.
The use of MMC Restricted Gauging and Sampling Equipment, in conjunction with MMC Vapor Control Valves is well known and established worldwide.
In keeping with a growing demand and in some cases prescribed legislation, MMC developed a Closed Hand Gauging System, which has the same gauging feature as its Restricted Hand Gauging Equipment.
The Closed Hand Gauging System, as does the Restricted Gauging System, allows an operator to determine cargo Ullage, Interface, and Temperature.
In addition, and as prime objective of the system design, operator exposure to product vapors is virtually eliminated.
As a natural next step in the development of equipment for use in Closed Applications, MMC has also developed the Closed Portable Sampling System. Information on the Closed Portable Sampling System is available upon request.
System Overview
MMC’s Portable Closed Sampling System and its sample collections valve, operate in conjunction with but independently of a cargo tank’s existing vapor control valve. Once the system is attached to any MMC vapor control valve, an operator can extract and bottle a product sample in place, without transfer of the collected sample to another container.
In addition, and as prime objective of the system design, operator exposure to product vapors, and the traditional physical handling of the collected products, has been greatly reduced.
The system is gas tight and has been designed to meet or exceed the current vapor control regulations.
To achieve the above design goals, the system uses a unique combination of vapor return hose assembly, sample collection valve and sample bottle fill attachment.
System operation is simple, easily understood, and not complicated using laboratory type accessories.
The entire system is made in the U.S.A.
