TTFM 6.1 Transit Time Flow Meter
ENCLOSURE INSTALLATION
Locate the enclosure within 25 ft (7.6 m) of the sensors (up to 100 ft - 30 m optional). The enclosure can
be wall mounted with the four mounting screws (included) or panel mounted with Option PM Panel
Mount kit from Greyline Instruments.
Avoid mounting the enclosure in direct sunlight to protect the electronics from damage due to
overheating and condensate. In high humidity atmospheres, or where temperatures fall below freezing,
Option TH Enclosure Heater and Thermostat is recommended.
IMPORTANT
: Seal conduit entries to
prevent moisture from entering enclosure.
NEMA4X (IP66) WITH CLEAR COVER
1. Open hinged enclosure cover.
2. Insert #12 screws (supplied) through the four enclosure mounting holes to
secure the enclosure to the wall or mounting stand.
Additional conduit holes can be cut in the bottom of the enclosure when
required. Use a hole saw or Greenlee-type hole cutter to cut the required
holes.
IMPORTANT
: DO NOT make conduit/wiring entries into the top or sides
of the enclosure.
Note: This non-metallic enclosure does not automatically provide grounding between conduit
connections. Grounding must be provided as part of the installation. Ground in accordance with the
requirements of the National Electrical Code. System grounding is provided by connecting grounding
wires from all conduit entries to the steel mounting plate or another point which provides continuity.
CLEANING
Cleaning is not required as a part of normal maintenance.
