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

Floating roof tank

Covered floating roof tank

Pressurized or bullet tank

Tank with agitator or heavy turbulence

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

Endress+Hauser 17

Installation Proservo NMS81

• 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 ).

5.1.4 Mounting with a stilling well

The stilling well diameter that is required to protect the measuring wire without disturbing its operation varies depending on the tank height. The stilling well could either be of constant diameter, or narrower at its upper part and wider at its lower part. The following figure shows two examples of the latter case, namely a concentric stilling well and an asymmetric stilling well.

• L3: length from center of the calibration window to the bottom of the flange (77 mm (3.03 in) + flange thickness). For JIS 10K 150A RF, the flange thickness is 22 mm (0.87 in).

• When using an asymmetric stilling well, take into account the lateral shift of the displacer and follow the NMS8x mounting direction as shown in the figure.

• To calculate the required stilling well diameters, the formula below should be used. The following tables contain the necessary parameters in order to calculate the dimensions of the stilling well. Be sure to have appropriate dimensions of the stilling well according to each dimension in the table.

• The radial direction offset (r) is required for only the 47 m (154.20 ft) and 55 m (180.45 ft) wire drum. For all other drums, the offset is 0 mm/in.

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.

• Coat or paint the interior surface of the pipe to prevent corrosion.

• 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.

Guide wire installation

Guide wire installation procedure

1. Install NMS8x [1] on the reducer plate.

2. Perform calibration steps (→  87) 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.

5.1.6 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.

 12 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, →  97). 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.

5.1.7 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.

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
