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.

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

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.

5.1.3 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

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.

7.8.2 Analog output (4...20mA)

Each Analog I/O module of the device can be configured as 4...20mA analog output. To do so, assign appropriate values to the following parameters:

Setup → Advanced setup → Input/output → Analog I/O

Parameter Meaning / Action

Operating mode Select 4..20mA output.

Analog input source Select which tank variable is transmitted via the analog output.

Analog input 0% value Specify which value of the tank variable corresponds to an output current of 4 mA.

Analog input 100% value Specify which value of the tank variable corresponds to an output current of 20 mA.

7.8.3 Modbus

Depending on the order code the device may have up to two Modbus communication interfaces. These are configured in the following submenus:

• Setup → Advanced setup → Communication → Communication interface 1 to 2 → Configuration

• Setup → Advanced setup → Communication → Communication interface 1 to 2 → Integer conversion

7.8.4 V1

Depending on the order code the device may have one V1 communication interface. It is configured in the following submenus:

• Setup → Advanced setup → Communication → Communication interface 1 → Configuration

• Setup → Advanced setup → Communication → Communication interface 1 → V1 input selector
