1.1 Designated Use
Average Temperature Prothermo NMT539 is a multi-spot Pt100 average thermometer combined with
a local HART signal converter to meet the demand of temperature measurement for inventory control
applications. NMT539 consists of Max. 6 temperature elements which have different length with fixed
(2m or 3m) interval. It is best suited connected to Proservo NMS5, or Endress+Hauser Micropilot S-
series radars and the Tank Side
Monitor NRF590. Mounted on the tank top, NMT539 provides temperature information on the two
wire, intrinsically safe (i.s.) powered local HART loop.
1.2 Installation, Commissioning, and Operation
• Mounting, electrical installation, start-up, and maintenance of the instrument may only be per-
formed by trained personnel authorized by the operator of the facility.
• Personnel must read and understand these installation instructions before performing the proce-
dures.
• The instrument may only be operated by personnel who are authorized and trained by the operator
of the facility. All instructions in this manual must be observed.
• The installer must make sure that the measuring system is correctly wired according to the wiring
diagrams. The measuring system must be grounded.

3.2.3 Flexible Tube Procedure
Do not hold the flexible tube at a single point and lift the sensor. This may cause damage to the tube.
Figure 16: Flexible Tube-1
When winding the flexible tube, keep the diameter of the tube at a minimum of 1m (39.37") or more.
When bending the flexible tube to attach to a tank, the radius of curved area must be 500mm (19.69")
or more.
Figure 17: Flexible Tube-2
If the radius of the curved area must be shown above becomes smaller than 500mm (19.69"), the flex-
ible tube or the measuring element may be seriously damaged or broken.

3.2.4 Mounting of NMT539 Procedure
• The flexible tube length of NMT539 is defined for the customer’s specifications. Before mounting,
check as follows:
1. Tag Number (if any) on the body of NMT532
2. Length of Flexible Tube
3. Number of Measuring Points
4. Intervals between Measuring Points
• Mount NMT539 at a minimum of 500mm(19.67") away from the tank shell. This will ensure that
the measurement is not influenced by changes in ambient temperature.
• The procedure for mounting of NMT539 on a tank varies depending on the type of tank. Procedures
for a fixed roof tank and a floating roof tank are shown in this section as examples. However, pro-
cedures for mounting of the flexible tube head are the same (mounted on the top of the tank) in any
types of tanks.
• The recommended standard diameter of nozzle is 50mm (2").
Figure 18: Mounting NMT539
Wrapping Sealing Tape Procedure
Wrap the sealing tape around the screwed part shown below at a width of 30mm (1.18") or more to
maintain high level of air sealing between flanges.
1. When the installation height of the probe is set, lift the probe and mark the position of the bottom
of the flange.
2. Turn the flange and moves it up toward the converter unit approximately 30mm (1.18").
3. Wrap sealing tape (e.g. material: PTFE or other appropriate materials) around the adjusting pipe
below the bottom of the flange.
4. Turn the flange back to the marked installation (original) height.
5. Wrap sealing tape around the adjusting pipe above the flange.
6. Turn the lock nut downwards to the flange until it is properly secured.
This completes the wrapping sealing tape procedure.

Ensure to keep the tension at of 16kg or less during setting and after setting. Exceeding the limit may
cause breakage in the flexible tube.
Figure 20: Mounting Accessory
Safety Precaution for Use of NMT539 at Temperature of -170°C
When NMT539 is installed in cryogenic tanks, pressure in the flexible tube and electrical housing may
decrease due to the rapid cooling of the tank processes. During commissioning of the temperature
probe, loosen the terminal compartment cover to stabilize the pressure.
When removing NMT539 from a cryogenic tank, the temperature and pressure in the flexible tube
may rapidly increase due to an extreme temperature difference between the inside and outside of the
tank. In this case, the flexible tube may move in an uncontrolled manner, and could lead to mechanical
damage or personal injury.
To prevent this, turn off the power and loosen the terminal compartment cover to stabilize the pres-
sure.

3.3 Mounting NMT539 on Various Tanks
When installing water bottom, check "Zero" reference position of water bottom compared with manual
dipping reference.
3.3.1 Mounting NMT539 on Fixed Roof Tank
There are three methods for mounting NMT539 on a fixed roof tank:
• Top Anchor Method
• Stilling Well Method
• Anchor Weight Method
If a heating coil is attached to the bottom of the tank, the clearance between the bottom hook of the
flexible tube and the bottom of the tank may vary depending on the type of heating coil.
Top Anchor Method
The flexible tube and water bottom sensor are fixed with a wire hook and a top anchor.
Figure 22: Top Anchor Method
Top Anchor Attachment Procedure
1. Insert a flexible tube and/or WB (Water Bottom) probe into a gasket and lower the flexible tube
from the nozzle at the top of the tank.
The flexible tube and/or WB probe must be lowered carefully without overbending and scratching the
inner edge of the nozzle hole.
2. Rotate NMT539 for cabling in the most convenient way.
3. Straighten the tensioning wire, temporarily fix the end of the wire to the top anchor and lower
the wire.

4. Put the tensioning wire into the wire hook at the bottom of the tank.
5. Secure the tensioning wire twice through the hole at the bottom hook
6. Wind the provided wire around the tensioning wire to secure the tensioning wire.
Figure 23: Top Anchor Attachment-1
7. Using bolts, fix the mounting flange of Prothermo to the nozzle at the top of the tank.
Keep the compression of the spring of 35 to 37mm (1.38 to 1.47 inch). Compression exceeding the
spring of 35 to 37mm may damage the sensor.
8. Draw the end of the tensioning wire as much as possible by hand and foot.
9. Bend the wire and fix it using the nut.
10. Cut the excess wire.
11. Screw the nut to compress down the spring of the top anchor from 35 to 37mm.
12. Cover the top anchor.
This completes the mounting top anchor procedure.
