Basic safety instructions Proservo NMS83

2 Basic safety instructions

2.1 Requirements for the personnel

The personnel for installation, commissioning, diagnostics and maintenance must fulfill the following requirements:

Trained, qualified specialists must have a relevant qualification for this specific function

‣

and task. Are authorized by the plant owner/operator.

‣

Are familiar with federal/national regulations.

‣

Before starting work, read and understand the instructions in the manual and

‣

supplementary documentation as well as the certificates (depending on the application). Follow instructions and comply with basic conditions.

‣

The operating personnel must fulfill the following requirements:

Are instructed and authorized according to the requirements of the task by the facility's

‣

owner-operator. Follow the instructions in this manual.

‣

2.2 Designated use

Application and measured materials

Depending on the version ordered, the measuring device can also measure potentially explosive, flammable, poisonous and oxidizing media.

Measuring devices for use in hazardous areas, in hygienic applications or in applications where there is an increased risk due to process pressure, are labeled accordingly on the nameplate.

To ensure that the measuring device remains in proper condition for the operation time:

Only use the measuring device in full compliance with the data on the nameplate and

‣

the general conditions listed in the Operating Instructions and supplementary documentation. Check the nameplate to verify if the device ordered can be put to its intended use in the

‣

approval-related area (e.g. explosion protection, pressure vessel safety). Use the measuring device only for media against which the process-wetted materials

‣

are adequately resistant. If the measuring device is not operated at atmospheric temperature, compliance with

‣

the relevant basic conditions specified in the associated device documentation is absolutely essential. Protect the measuring device permanently against corrosion from environmental

‣

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.

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 ).

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.

• 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.

• 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.
