MMC USA sampling ruler, Restricted type is designed to suit most types of MMC stop valves. Each sampling ruler consists of a ruler with a head hook, a 1/2-liter sampling tank, and a copper berries according to API standards.
Specialized rulers for hand sampling, level measurement or drying of the bottom of the cargo cellar. Similar to a closed type sampling ruler, the limited-type sampling ruler can be fitted to most MMC blocking valves, conduct sampling inside the tank, then close the valve, remove the ruler from the valve, and use your hands to pour the sample into the container. The ruler can be transferred to the level measurement function or check the dryness of the container by attaching the berries to the end of the ruler wire.

Flexi-Dip RESTRICTED Sampling Tape Systems (Minimal Gas Leakage)
Flexi-Dip Restricted Sampling Tape systems are available for use with MMC’s various vapor-control valves. Each Flexi-Dip Sampling Tape comes complete with tape with snap hook, 1/2 liter sampler and Std. API brass bob.Restricted tapes are designed for manual sample collection, sounding and tank bottom dryness checking. Similar to the FIPS system, once the Restricted sampling unit is attached to any existing MMC vapor-control valve, it can extract a sample in place but then requires valve closure, removal from the valve and manual dumping of the collected product. Standard sounding and tank bottom dryness checks can also be performed.
