6 InPro 7100-VP Series

4-electrode sensors are so-called diffuse-field sensors. The individually

determined cell constant was established under laboratory conditions without external influences.

Depending on the installation configuration, external influences (e.g. from

the pipe) can result in a shift in cell constant. If the application does not guarantee a minimum clearance of 30 mm (1.18") around the sensor, it is recommended to carry out recalibration of the sensor in installed position.

Packaging

The packaging consists of cardboard and plastic material. Keep the packaging for later use during storage or for transportation of

the sensor. Should you wish to dispose of the packaging material, please observe your local regulations as well as those data and instructions given in Chapter 5.3 of this manual.

Unpacking and inspection Please check the sensors immediately during unpacking in order to determi-

ne possible damage or missing items. Any irregularities should immediately be reportet to your carrier and to your supplier.

Each InPro 7100-VP Series sensor is equipped with an integral tempera ture

probe Pt 1000, IEC 751 Class A.

–1

The nominal cell constant is 0.25 cm

. The exact value is printed on the sensor label. For each sensor, the cell constant and temperature constant have been measured/established individually and the values have been documented in the accompanying Quality Certificate. All calibrations can be traced back to NIST and /or ASTM Standards.

Both the measuring range and the system measurement accuracy strongly

depend upon which type of transmitter is employed.

2.1 Application compatibility

The wetted material parts of the sensor (several different materials come

into contact with the sample medium) can under some circumstance be incompatible with the particular composition of the process medium and/or of the operating conditions. Responsibility to verify application compatibil ity lies wholly with the user.

The compatibility of different types of material are outlined on http://www.coleparmer.com/techinfo/chemcomp.asp. Mettler-Toledo GmbH, Process Analytics accepts no responsibility whatso-

ever for the correctness or accuracy of such details.

2.2 Proper utilization

METTLER TOLEDO InPro 7100-VP Series sensors are intended solely for

the precise measurement of conductivity in aqueous solutions in industrial applications.

Any other use, or any operation over and above that intended by the

InPro 7100-VP Series © 02 / 2017 Mettler-Toledo GmbH, CH - 8606 Greifensee 52 002 092 Printed in USA

manufacturer, are not recommended and can lead to harm or injury to material/equipment and persons. This is also relevant for applications which do not comply with the technical data labeled on the sensor. For any damage arising from such misuse, the user assumes full and sole responsibility.

2.3 Safety measures

The InPro 7100-VP Series sensors have been manufactured in line with

state-of-the-art technology and in accordance with accepted technical safety regulations. Nevertheless, the sensors can still represent a source

of risk and danger: – if the sensors are operated by insufficiently trained personnel, – if the sensors are employed incorrectly or not as intended by the manufacturer, – if the sensors are not regularly maintained or serviced.

Local legislation and regulations must be observed at all times. Such

stipulations do not form an integral part of this instruction manual. It is necessary to use protective gear, including gloves, for persons coming

in contact with the fluid. It is recommended to use gloves when handling

the electrodes of the sensor to limit contamination of the sensor. The user is responsible for the instruction and training of personnel. Addi-

tional copies of the instruction manual can be ordered from your supplier.

This instruction manual is an essential element of the sensor equipment

and must at all times be readily available to operators directly at the mea-

surement site. Before the sensor is removed from the process/process adapter, it must be

ensured that the process pressure has been reduced to a safe level and the

process temperature lowered to a safe range. Any escape of hot process

fluid under pressure can cause damage to material/equipment or injury to

persons. No modification whatsoever may be carried out on the sensors. Any

unauthorized modification or manipulation of the sensors results in imme-

diate expiration of the full scope of warranty granted by the manufacturer.

3 Initial start-up

3.1 Installation

The sensors are to be mounted in such a way that the sample medium

flows directly into the sensor through the orifice at the tip and re-emerges through the vent holes. Any other installation position of the sensors can create the risk of formation of airlocks, or of contamination through deposits of solid matter.

Flow direction

T-piece

> R 30

Sensor

Flow of medium must be accross the face of the sensor. Air bubbles and

solid matter deposits are to be avoided. A minimum clearance of 30 mm (1.18") between sensor and pipe wall must be maintained (see drawing above).

Vertical mounting (top entry) in a pipe is recommended only if the pipe is

full and no air bubbles are able to develop in the flow.

In the event of side mounting (side entry) of the sensor, vertical upward

flow of sample process medium must be ensured.

4. Maintenance and troubleshooting

4.1 Conditions of warranty

METTLER TOLEDO guarantees the quality of materials and workmanship

within a narrow range of manufacturing tolerances, so that the product purchased is free from any substantial deviations from material and manufacturing quality standards. The warranty is valid for a period of one year from date of delivery (ex-works). If within this warranty period, any repair or replacement should become necessary, and such cause is not due to misuse or incorrect application, please return the sensor, freight pre-paid, to your appropriate METTLER TOLEDO agency. Repair work will be carried out free of charge. Final decision on whether the defect is due to a manufacturing error or to incorrect operation of the sensor by the customer is made at the discretion of the Customer Service department of METTLER TOLEDO. After expiration of the warranty period, faulty sensors will be repaired or replaced on an exchange basis against payment of the costs involved.

4.2 Maintenance

Dirty or contaminated sensors can deliver incorrect measurement values.

If fouling is presumed, the sensor is to be removed from operation and the electrodes as well as the insulation between the electrodes cleaned with a soft cloth. Do not clean electrodes with an abrasive paper or pad. Suitable cleaning solutions are mild detergents or strongly diluted acids (< 0.5 % by wt.) such as nitric acid. Never use clean ing agents that

are not compatible with the material to be cleaned. When handling acids, precautionary measures are to be taken. The sensor must be thoroughly flushed with distilled or distilled water

prior to re-installation. Following cleaning and re-installation into the process, it can take from

several minutes up to several hours until the sensor delivers the originally

measured value.

5 Removal from operation, storage, disposal

5.1 Removal from operation

The sensor is only conditionally subject to aging. When used as intended

and appropriately maintained and serviced, the lifetime of the sensor can

extend to several years. Before removing the sensor from the process/process adapter, it must be

ensured that the process pressure has been reduced to a safe level and

the process temperature has lowered to a safe range. Any escape of hot

process medium under pressure can cause damage to material/equipment

or injury to persons. After removal from the process the sensor should first be flushed with

distilled water. If the sensor incurs a defect, it can not be repaired and must be disposed

under observance of prevailing local regulations.

5.2 Storage

If the sensor is not use, it can be stored dry. However, it has to be recon-

ditioned in the process fluid accordingly prior to renewed operat ion. This

procedure may take several hours to complete.

5.3 Disposal

The user is responsible for the proper disposal of the conductivity sensor. The

sensor contains electronic components that must be disposed of correctly

in order to avoid hazards to people or to the environment.
