influences.
‣Observe the limit values in the "Technical Information".
The manufacturer is not liable for damage caused by improper or non-designated use.
Residual risk
During operation the sensor may assume a temperature near the temperature of the
measured material.
Danger of burns due to heated surfaces!
‣For high process temperatures: Install protection against contact in order to prevent burns.
2.3 Workplace safety

‣Use original spare parts and accessories from the manufacturer only.
Hazardous area
To eliminate a danger for persons or for the facility when the device is used in the hazardous
area (e.g. explosion protection, pressure vessel safety):
‣Based on the nameplate, check whether the ordered device is permitted for the intended
use in the hazardous area.
‣Observe the specifications in the separate supplementary documentation that is an integral
part of these Instructions.

5 Installation
5.1 Requirements
5.1.1 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°
1
A0026889
 2 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.

Proservo NMS83 Installation

5.1.2 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
When NMS8x is delivered, the displacer is always shipped separately and there are two
methods to install displacer as follows.
• Installation for displacer shipped separately method
• Installation through the calibration window
5.2.1 Available installations
The following installation procedures are available for NMS8x.
