Proservo NMS83 Installation

5 Installation

5.1 Requirements

5.1.1 Type of tanks

Depending on the type of tank and application, different installation procedures are
recommended for NMS8x.

Type of tanks Without guide system With stilling well With guide wires

Fixed roof tank

A0032437 A0032438 A0032439

Tank with agitator or heavy
turbulence

A0032440 A0032441

• A stilling well is required in a floating roof tank and a covered floating roof tank.

• Guide wires cannot be installed in a floating roof tank. When the measuring wire is
exposed to free space, it may break due to an external shock.

• Installing guide wires is not allowed in pressurized tanks because the wires would
prevent closing the valve for replacing the wire, wire drum, or displacer. NMS8x
installation position is important for applications without the guide wire system in
order to prevent the measuring wire from being broken (refer to Operating
Instructions for details ).

Recommendations for NMS8x mounting with a stilling well

Follow the recommendations for mounting NMS8x with a stilling well.

• Keep the pipe connection welds smooth.

• When drilling holes into the pipe, keep the interior surface of the holes clear of
metal chips and burrs.

• Keep the pipe as vertical as possible. Check using a plumb bob.

• Install the asymmetric pipe under the valve and align the centers of the NMS8x and
the valve.

• Set the center of the lower part of the asymmetric pipe in the direction of the lateral
motion.

• Observe the recommendations as per API MPMS chapter 3.1B.

• Confirm grounding between NMS8x and the tank nozzle.

5.1.5 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.

 10 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,
→  89). 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.

1 Inlet pipe
2 Tank nozzle

• 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.

5.1.6 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.

• Operating via the remote display and operating module DKX001 (→  39) or the
local display and operating module at the device are equivalent.

• The measured value is indicated on the DKX001 and on the local display and
operating module simulataneously.

• The operating menu cannot be accessed on both modules at the same time. If the
operating menu is entered in one of these modules, the other module is
automatically locked. This locking remains active until the menu is closed in the
first module (back to measured value display).

7.3.1 Display and operating elements

The device has an illuminated liquid crystal display (LCD) that shows measured and
calculated values as well as the device status in the standard view. Other views are used to
navigate through the operating menu and to set parameter values.

The device is operated by three optical keys, namely "-", "+" and "E". They are actuated when
the appropriate field on the protective glass of the front is touched with the finger ("touch
control").

7.3.8 Access code and user roles

Meaning of the access code

An access code can be defined in order to distinguish between the following user roles:

User role Definition

Maintenance • Knows the access code.

• Has write access to all parameters (except service parameters).

Operator • Doesn't know the access code.

• Has write access to only a few parameters.

• The description of parameters states which role is needed at least for read and write
access to each parameter.

• The current user role is indicated by the Access status display parameter.

• If the access code is "0000", every user is in the Maintenance role. This is the
default setting on delivery of the device.

Defining an access code

1. Navigate to: Setup → Advanced setup → Administration → Define access code
→ Define access code

2. Enter the intended access code (max. 4 digits).

3. Repeat the same code in the Confirm access code parameter.
 The user is in the Operator role. The -symbol appears in front of all write-

protected parameters.

Switching to the "Maintenance" role

If the -symbol appears on the local display in front of a parameter, the parameter is
write-protected because the user is in the Operator role. To switch to the Maintenance
role, proceed as follows:

1. Press .
 The input prompt for the access code appears.

2. Enter the access code.
 The user is in the Maintenance role. The -symbol in front of the parameters

disappears; all previously write-protected parameters are now re-enabled.

Switching back to the "Operator" role automatically

The user automatically switches back to the Operator role:

• if no key is pressed for 10 minutes in the navigation and editing mode.

• 60 s after going back from the navigation and editing mode to the standard view
(measured value display).

The level measurement is to measure the position where the displacer is balanced
(immersion point) in the liquid. When the liquid surface level changes, the displacer
continuously follows the position to measure the liquid level. To define the appropriate
level measurement, the following settings are required prior to operation.

The interface measurement can determine the interface between different liquids in a tank
(e.g. water and oil).Up to two different interfaces can be determined within a maximum of
three phases in a tank.

Setting the density of application

Density values for three liquid phases are set as follows prior to delivery.

• Upper density: 800 kg/m

• Middle density: 1 000 kg/m

• Lower density: 1 200 kg/m

Change the data to reflect the actual density values. For tanks with only one liquid phase,
set the upper density. For tanks with two or three phases, set middle and bottom densities
as well.

Number of phases Parameters to be set

1 phase Upper density

2 phases Upper/middle density

3 phases Upper/middle/lower density

When performing an interface measurement, the minimum density difference
between phases should be at least 100 kg/m3.

Setting the density
