Float Probe Assembly
The float probe assembly helps prevent liquid from being drawn into the
EAGLE 2. The float probe assembly is 12-feet long. The hose between both
ends of the float probe has an integral cable that connects a switch in the float
end to the plug at the other end. This plug connects to the float probe socket
that is adjacent to the EAGLE 2’s IR port. A quick connect fitting at the same
end of the assembly connects to the EAGLE 2’s inlet fitting. The float probe
switch at the opposite end of the 12-foot hose shuts off the pump if the probe
begins to be submerged into a liquid.

To use the float probe assembly:
CAUTION: Drawing water, gasoline, or other liquids into the EAGLE 2 will
cause damage.
1. Attach the quick connect fitting to the EAGLE 2’s inlet fitting.
2. Insert the plug into the socket that is adjacent to the IR port.
3. Lower the probe into the tank or vessel. Lower the probe very
slowly, keeping the float switch vertical, to allow the float switch to
activate if necessary.
Dilution Fitting (1:1)
CAUTION: When measuring oxygen readings, remove the dilution fitting
or use your finger to seal the small dilution hole on the side of
the dilution fitting.
The catalytic combustible gas sensor requires oxygen to operate. In
environments where there is not enough oxygen to operate the combustible
gas sensor, (for example a tank purged with an inerting gas), the 1:1 dilution
fitting adds sufficient oxygen by blending ambient air with the incoming
sample. The standard dilution fitting dilutes at a ratio of 1:1 (one part air to
one part sample). The dilution fitting is not an integral part of the float probe
