ACM 150
Sample tubing and filters
Tubing material
Tubing is used to connect the ACM 150 monitor to the monitored sample points. The
requirements for tubing are:
Size
Recommended Material
Alternate Material
Unacceptable Tubing
NOTE
If metal tubing is required by fire
code, use 316 SS tubing or run
Teflon or polypropylene in metal
conduit. Before using SS tubing,
consult with Honeywell Analytics
about material compatibility.
CAUTION!
Tygon, polyethylene, copper and aluminum absorb or react with many gases.
Use only the materials listed above. Make no substitutions.
MISE EN GARDE!
Tygon , le polyéthylène, le cuivre et l'aluminium absorbe ou réagir
avec de nombreux gaz . Utilisez uniquement les matières énumérées
ci-dessus . Ne faites pas de substitutions .
Tubing run lengths
The ACM 150 monitor should be located near the areas it samples to minimize tube
lengths and response time. The maximum distance for tubing is 750 feet (230 meters)
or 500 feet (150 meters) when composite sampling mode is used. Prevent leaks
in sample tubes by making continuous runs with no fittings or unions, if possible.
Discard short lengths that are left over instead of joining them to make longer runs.
ACM 150 tube connection points
Each sample tube is connected to an inlet on top of the ACM 150 monitor using 3/8
inch Swagelok tube fittings. The inlet fittings are numbered from 1 to 40, as shown in
Figure 26.
3/8 inch O.D. by 1/4 inch I.D.
PFE Teflon, 500 foot rolls
Polypropylene, such as Parker PP-
64 (500 foot roll) or equal quality.
Polypropylene is acceptable for most
gases that are not reactive (not suitable
for mineral acid gases)
• all other plastics
• all other metals
• tubing with a smaller OD than 3/8
inch
• thin wall tubing that can kink when
bent
