INSTALLATION MT100 Multipoint Flow Meter
Cabling Entry
Cable entries for flow element and remote electronics enclosures are made via cable glands. Refer to APPENDIX A for specific information.
Cable Gland
A cable gland provides cable strain relief as well as a barrier against moisture. Follow the instructions below for cable gland installation.
The following applies to applications using the Capri ADE 1F2 model cable gland with NPT thread and 316L stainless
steel construction. Use only cable glands and/or conduit fittings that meet or exceed the approval rating of the area in
which the instrument is installed.
1. Remove perforated center of sealing ring, shown in Figure 29 below, by pushing through with a blunt object. Do not use cable to remove
silicone center as this may damage cable or cable gland assembly. Cable gland may be completely assembled during this step.
2. Loosen cable gland and apply plant approved thread lubricant to tightening nut threads as shown in Figure 29 below. FCI
recommends use of HTL4 or similar thread lubricant. Use sparingly.
3. Ensure correct orientation of skid washer shown in Figure 29 detail below. This is necessary for proper seal on cable.
4. Hand thread tightening nut but do not tighten fully.
5. Clean and degrease cable gland assembly with plant approved cleaning solution/solvent so that all outer surfaces are free of any
lubricant or grease.
6. Thread cable through cable gland.
7. Ensure an adequate length of cable wires are within the enclosure, then tighten cable gland finger-tight.
8. After all enclosure connections are made, torque cable gland tightening nut to about 44.3 in-lb (5 N-m).
9. Clean off any excess lubricant.
