DFS 5.1 Doppler Flow Switch
APPENDIX A - OPTIONS
EXTRA SENSOR CABLE
(OPTION DXC)
Each Greyline flow switch includes 20 ft. (6m) shielded coaxial pair cable. Additional cable and Cable
Junction Box (Option JB2X) may be ordered with the Flow Switch, or the cable may be spliced and
extended up to 500 ft (152m) as required during installation. No adjustment is required when the sensor
cable is extended or shortened.
Use only Greyline shielded coaxial pair cable. Extended sensor cable can be installed in conduit for
mechanical protection. Recommended installation with a JB2X junction box is illustrated below:
Note: Instead of Greyline Option DXC shielded coaxial pair, you may substitute RG174U coaxial cable
from your local electrical cable distributor but this cable is not shielded so extended cable must be
installed in metal conduit.
COAXIAL CABLE PREPARATION
DXC Doppler sensor cable can be cut and spliced up to a maximum length of 500 ft (152 m). Cable ends
must be prepared as illustrated below.
