Guide wire installation
Guide wire installation procedure
1. Install NMS8x [1] on the reducer plate.
2. Perform calibration steps (→  44) before the displacer [3] is attached to the guide
wires.
 Make sure that the displacer does not touch the guide wires during calibration. This
could be done by mounting the NMS8x to the reducer plate [2] prior to fitting the
guide wires [4].
Perform calibration steps so that displacer does not touch the guide wires if the guide
wires are already installed to the reducer plate.
3. Secure the guide wires to the hooks of the springs [5].
4. Secure the springs to the reducer plate.
5. Put the guide wires through the displacer guide ring [6] and set the displacer.
This completes the guide wire installation procedure.

5.1.2 Alignment of NMS8x
Flange
Confirm that the size of the nozzle and the flange is matched prior to mounting NMS8x on
the tank. The flange size and the rating of NMS8x vary depending on the customer’s
specifications.
• Check the flange size of NMS8x.
• Mount the flange on the top of the tank. The deviation of the flange from the
horizontal plane should not exceed +/- 1 degree.
• When mounting NMS8x on a long nozzle, make sure that the displacer does not touch
the inner wall of the nozzle.
+1°
-1°

A0026889
 4 Allowable inclination of mounting flange
1 Nozzle
When NMS8x is installed without a guide system, follow the recommendations below:
• Confirm the mounting nozzle is in the sector between 45 and 90 degrees (or -45 and
-90 degrees)away from the inlet pipe of the tank. This prevents heavy swinging of the
displacer caused by waves or turbulence from the inlet liquid.
• Confirm the mounting nozzle is 500 mm (19.69 in) or more away from the tank wall.
• Confirm the minimum measuring level is at 500 mm (19.69 in) or more above the top
of the inlet pipe by setting the low stop (for details of low stop setting, refer to
"Commissioning" in the separate BA (Instruction Manual)). This protects the displacer
from direct flow of the inlet liquid.
• If a stilling well cannot be mounted in the tank due to the shape or condition of the
tank, attaching a guide system is recommended. Consult E+H services for further
information.

• Before pouring liquid into the tank, confirm that liquid flowing through the inlet of the
pipe will not contact the displacer directly.
• When discharging liquid out of the tank, ensure that the displacer will not get caught
in the liquid current and sucked into the outlet pipe.

5.1.3 Electrostatic charge
When liquid measured by NMS8x has a conductivity of 1 uS/m or less, it is quasi-
nonconductive. In this case, using a stilling well or guide wire is recommended. This releases
the electrostatic charge on the liquid surface.
5.2 Mounting of the device
The NMS8x is delivered in two different packing styles depending on the mounting method of
the displacer.
• For the all-in-one method, the displacer is mounted on the measuring wire of NMS8x.
• For the displacer shipped separately method, it is necessary to install the displacer on the
measuring wire inside NMS8x.
5.2.1 Available installations
The following installation procedures are available for NMS8x.
