§
Objects which are not electrically conductive such as wooden or fiberglass buildings,
non-reinforced masonry, trees, plastic, and glass have less effect on radio signals
than metal objects.
§
Windows and wooden doors can provide radio signals access into otherwise closed
metal buildings. However, “low-E” window glass and bulletproof glass may have a
thin metallic coating that can reflect radio signals.
§
Strong electromagnetic fields such as those found in close proximity to power lines,
large electric motors, generators, electric fences, and transmitter antennas may
interfere with the radio signals received by the Receiver.
§
The Receiver should be mounted as high as is reasonably possible to improve its
ability to receive radio signals. For example, placing the Receiver on a high shelf
would be preferable to setting the unit on a floor near ground level. Installing the
Receiver on the second floor of a two-story structure would be more desirable than
installing it on the ground floor. Installing the Receiver in an underground basement
should be avoided.
3.2 Handling
Guidelines
The Digital Two Channel Monitor is designed to provide many years of reliable service
in demanding outdoor environments. However, the Monitor contains sensitive circuitry
and should be handled carefully. Do not throw or drop the Monitor. Do not attempt to
disassemble the Monitor except as described in section 5.1 (Battery Replacement).
3.3 Mounting
After the High Level Alarm Console or Controller has been successfully setup, the Float
Switch Assembly and Digital Two Channel Monitor can be mounted on the tank by
following these instructions:
Warning: Tanks may contain flammable liquid or vapor, extinguish all flames and
smoking material before performing the Monitor installation procedure
Step 1.
Select a mounting bung on the top of the tank that will keep the Float Switch Assembly
vertical and allow free travel of the float mechanism. Verify that there is adequate
clearance to prevent the float mechanism from contacting obstructions such as walls,
baffles, reinforcements, and other measurement equipment inside the tank. Remove all
materials from the desired bung.
