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.

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

A0026890

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 quasi­nonconductive. 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.
