AVFM 6.1 Area-Velocity Flow Meter
APPENDIX A – OPTIONS
EXTRA SENSOR CABLE
(OPTION VXC)
Each Greyline AVFM 6.1 flow meter includes 25 ft. (7.6 m), 50 ft. (15 m) or 100 ft. (30 m) tri-coaxial
sensor cable. This cable is shielded from electrical interference and is watertight with a polyurethane
jacket. Additional cable and Cable Junction Box (Option JB2X or JB4X) may be ordered with the flow
meter, or the cable may be spliced and extended up to 500 ft (152 m) total length as required during
installation. No adjustment is required when the sensor cable is extended or shortened. Use only
Greyline tri-coaxial VXC shielded cable, or run three RG174U coaxial cables in a metal conduit.
Extended sensor cable should be installed in rigid metal conduit for mechanical and electrical noise
protection. Recommended installation with a junction box is illustrated below:
