TOANSMITTEO INSTALLATION
Unpacking and Inspection
Upon opening the shipping container, visually inspect the product and applicable accessories for any physical damage such
as scratches, loose or broken parts, or any other sign of damage that may have occurred during shipment
OTEE:
N
If damage is found, request an inspection by the carrier’s agent within 48 hours of delivery and file a claim with the
carrier A claim for equipment damage in transit is the sole responsibility of the purchaser
Mounting Location
The enclosure should be mounted in an area that is convenient for servicing, calibration and for observation of the
LCD readout
1 Locate the transmitter within the length of transducer cable that was supplied with the DFX system If this is not possible,
exchange the cable for one that is of proper length While transducer cable extension is not generally recommended,
if additional transducer cable length is required, use cable and connectors of the correct type and impedance In many
cases, especially if a splice my be exposed to water or other liquids, it may be more effective to replace the entire cable
Transducers use RG59,75 Ohm coaxial cable or Twinax (Belden #9463) or
(Belden # 9463DB) 78 Ohm two-conductor cable
2 Mount the DFX flow meter in a location that is:
• Free of vibration
• Protected from falling corrosive fluids
• Within ambient temperature limits – 40…185° F (– 40…85° C)
• Out of direct sunlight Direct sunlight may increase transmitter temperature to above the maximum limit
3 See
for enclosure and mounting dimension details Make sure there is enough room for door swing, maintenance
and conduit entrances Secure the enclosure to a flat surface with four appropriate fasteners
4 Use conduit hubs where cables enter the enclosure Seal unused holes with plugs
OTEE:
N
Use NEMA 4 (IP-65) rated fittings/plugs to maintain the watertight integrity of the enclosure Generally, the left
conduit hole (viewed from front) is used for line power, the center conduit hole for transducer connections and the
right hole is used for ISO-MOD I/O wiring
5 If additional holes are required, drill the appropriate size hole in the enclosure’s bottom Use extreme care not to run the
drill bit into the wiring or circuit cards
