Mag-FLEX Probe Length Calculation
Before ordering the Mag-FLEX Probe, an accurate dimension for “1” must be obtained. Measure internally the
Insertion Length of ‘1’ from the 1½” entry point to the bottom of the tank (see Figure 3). Probe length for ordering
purposes = Length of ‘1’ + 250 mm

Probe Handling
It is important to handle the Mag-FLEX probe with care at all times during the installation. Avoid excessive bending
of the probe especially at the points the ridged sections meet with the flexible shaft. Below you can see examples
of mishandling that would cause irreversible damage to the probe and invalidate the terms of warranty.

System Safety Layout
Conduit/ducting requirements are dependent on local electrical regulations.
Substitution of components may impair intrinsic safety. Probe, probe wiring and con-
sole wiring are intrinsically safe only when connected via this barrier.
Field Cable Ducting / Cable Trays
Explosion could occur if other wires share ducts with intrinsically safe cir-
cuits. Ducting from probes or sensors must not contain any other wiring.
FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS AND SAFETY PRECAU-
TIONS COULD CAUSE DAMAGE TO PROPERTY, ENVIRONMENT, RESULTING IN SE-
RIOUS INJURY OR DEATH.
Minimum diameters for underground probe ducting are:
• Up to 20 cables -100 mm diameter
• Up to 50 cables -150 mm diameter
Run suitable diameter cable ducting and / or cable trays from the TLS Console to each Mag-FLEX probe location.
For underground tanks, all cable duct entry points must be sealed to prevent the escape of hydrocarbon vapour and
liquid and the ingress of water. Cable duct & cable tray plans must be designed to suit local site requirements and
must conform to local/national regulations and industry standards.
For multiple TLS installations, the Mag Probe and Mag-FLEX cabling for one TLS system must be contained in
separate cable duct or tray to those cables belonging to another TLS system. Combining cables from different TLS
systems will be in violation of the intrinsically safe approval for this system and is not permitted. Combining cables
from different systems may also result in improper system operation.
Unless specified otherwise, any draw pits should be sited at 10 metre intervals or where acute cable duct angles are
unavoidable.
Ensure that all ducting is equipped with cable pull through ropes and that all visible cable ducts are properly fixed
and finished off in a neat and tidy manner.
All above ground cable runs should be properly secured and adequately protected from accidental damage.
Cable Specifications For Intrinsically Safe Apparatus Cabling
Cable must be installed to comply with local and national regulations in force at the time of installation. It is the
Installer’s responsibility to ensure that the installation complies with all relevant local and national legislation and
codes of practice.
Do not run the Mag-FLEX probe cable from the tank to the TLS Console in the same cable duct as non-intrinsically
safe wiring.
Gilbarco Veeder-Root requires the use of shielded cable for Mag-FLEX cabling. The cable must have a minimum
conductor CSA of 0.75 mm² and must meet with intrinsically safe system installation requirements. The cable
capacitance, inductance and L/R ratio must conform to the intrinsically safe output characteristics of the TLS
Console and the intrinsically safe input characteristics of the Mag-FLEX probe.
Field Cable, ATG to Probe, direct burial cable, V-R P/N 848100-2XX.
The TLS Console to Mag-FLEX probe cable length must not exceed 300 meters.

Mag-FLEX Installation & Handling Procedures
Probe Installation Requirements
Installation requires a minimum of two people to allow correct handling of the probe. Please note that the flexible
and therefore fragile nature of the Mag-FLEX probe makes it more prone to mechanical shock. The probe must not
be unpacked until it has been brought to its place of installation and where possible unpacked at the Tank top. The
probe corrugated shaft is supplied in a 1 meter diameter coil this coil MUST not be reduced in size. The packaged
curve is the maximum bend possible to prevent damage.
Miscellaneous Requirements
TANK ENTRY
The tank entry point provided must have an internal thread of 1½” BSP. Two optional adapters are available:
• Optional 1-1/2” BSP to 2” NPT adapter (P/N 579008-708)
• Optional 2” NPTF to 4” NPTF adapter (P/N 333535-001)
PROBE ASSEMBLY
The process connection, water float, product float, weight and magnet are shipped pre-assembled on the probe.
TOOLS AND MATERIALS
Before starting the installation you should have the following tools & materials:
• Mag-FLEX probe suitable for the tank height. See Mag-FLEX Probe Length Calculation on page 12.
• 2-Core probe cable run from TLS location to tank top. See Cable Specifications For I.S. Apparatus Cabling on
page 14.
• Optional junction box, part number 848100-004
• Non-sparking 55mm WAF (Width across Flat) spanner to tighten the 1-1/2” BSP process connection
• Non-sparking 65mm WAF spanner to tighten 2” NPT adapter (if used)
• Liquid sealing material for process connection, compatible with the tank material & product to be monitored
• Non-sparking Hexagon key (5mm) for the locking screw
• Non-sparking 30mm Spanner for the gland 30mm WAF (Width across Flat)
• Measuring tape to establish the correct position to lock the probe shaft into place
• For wireless installs - VR Kit 330020-770
• For hardwired installs - necessary conduit and seal offs as required
• Strap wrench (5-inch pipe capacity minimum)
