CLOSED and RESTRICTED SYSTEMS

	A Flexi-Dip standard CLOSED Sampling Tape System is shown above, left; a Flexi-Dip RESTRICTED Sampling Tape System is shown above, right. Typical 1/2-liter stainless steel sampler and a standard six inch API brass sounding bob are shown at center. Included as accessories with either sampling tape system are a 1/2 liter Stn. Stl. sampler, a 6" Brass Bob and a sturdy carrying case.

1. Standard Closed (FIPS) Sampling System

Once the (FIPS) sampling system 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 by attaching sampling bobs to the snap hook on the tape end header.

For other closed sampling systems, see the Product Sampling Tapes and Valves Systems page.

CLOSED SYSTEM SPECIFICATIONS

2. Flexi-Dip RESTRICTED Sampling Tape Systems (Minimal Gas Leakage)

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.

RESTRICTED SYSTEMS SPECIFICATIONS
Accuracy of Tape Reading:+/- 1/8 inch (3mm), +/- 0.01% of F.S. tape LGT (F.S. = Full Scale).
Application: R-Restricted sampling (1, 1/2- and 1/3-liter) through MMC vapor control-valve.
Tape Lengths: 50ft/15mm, 75ft/22.5mm 100ft/30m, 120ft/37m, stainless steel and plastic coated.
Typical Weights W/O Sampler: Reel, frame, tape, etc.

• 100 ft/30m for 1-liter sampling - 9 lbs (4.1kg).
