FLOW SWITCH SELECTION
GUIDE
Calibration:
flow stands are calibrated to the National Bureau of Standards
and Thomas Products LTD. recalibration schedule.
Model 1100
1. Replaceable switch capsule.
2. Salt spray and accelerated life
tested. Naval Sea Systems Command.
3. 25% heavier wall thickness, published
burst strength is derated.
4. Welding: Thomas Products LTD.
certified welders under requalification
system, performed in low hydrogen environment;
process schedules revision controlled.
Inspection 100‰ bubble tight, hydrostatic,
fluorescent penetrate.
5. True globe shaped housing yields

6. High pressure SST welded and
plugs.
7. Machining in-house, special modifications
available (i.e., NPT, BSPT, SAE, Silver
Braze, Socket, etc.).
Inspection using calibrated tools and gages
traceable to National Bureau of Standards
under Thomas Products LTD. recalibration
systems.

parts available.
3. Injection molding in-house, Thomas
Products LTD. can certify that only
virgin materials are used and no reprocessing
is done nor has color concentrate been
added during molding.
4. Periodic destructive testing,
i.e. verifying burst strength ratings.
5. Patented design SST clapper lower
P and helps pass particulates.
Patent Number 5, 162, 624
6. Accelerated life tested in a
variety of fluids.
7. UL recognized.
Typical Shuttle Type: A magnet equipped shuttle is displaced
at the proper calibrated flow of either
liquid or gas to actuate the hermetically
sealed reed switch.
At flow rates under the set point, clearance
is provided for the liquid of gas
to continue to flow.
When flow rates exceed the set pont the
shuttle or piston is displaced even
further to reveal a smooth, clear
opening for a low pressure drop.
