2 Safety instructions

• The unit described is a subcomponent for integration into a system.

– The system architect is responsible for the safety of the system.

– The system architect undertakes to perform a risk assessment and to create documentation in

accordance with legal and normative requirements to be provided to the operator and user of

the system. This documentation must contain all necessary information and safety instructions

for the operator, the user and, if applicable, for any service personnel authorised by the

architect of the system.

• Read this document before setting up the product and keep it during the entire service life.

• The product must be suitable for the corresponding applications and environmental conditions

without any restrictions.

• Only use the product for its intended purpose (Ò Intended use).

• Only use the product for permissible media.

• If the operating instructions or the technical data are not adhered to, personal injury and/or damage

to property may occur.

• The manufacturer assumes no liability or warranty for any consequences caused by tampering with

the product or incorrect use by the operator.

3 Intended use

The unit monitors liquids and gases.

It detects the process categories flow and medium temperature.

3.1 Application area

• Air

• Water

• Glycol solutions (reference medium: 35% ethylene glycol solution)

• Low-viscosity oils (viscosity: ≤ 40 mm²/s at 40°C /≤ 40 cSt at 104°F)

• High-viscosity oils (viscosity: ≥ 40 mm²/s at 40°C / ≥ 40 cSt at 104°F)

Electromagnetic compatibility (EMC):

This is a class A product. This product may cause radio interference in domestic areas:

uIf required, take appropriate EMC screening measures.

3.2 Restriction of the application area

• Rapid temperature changes:

Due to the thermal operating principle, the sensor tip placed in the medium must assume the

temperature of the medium in order to achieve the specified accuracy. Rapid and uneven

temperature changes can cause temporary misinterpretation.

• Temperature stratification:

There must be no temperature stratification in the medium to be measured. Temperature

differences within the cross section lead to misinterpretation of the measuring signal.

• Phase mixtures:

The medium to be measured must be completely mixed. Different thermal conductivities due to

phase differences lead to misinterpretation of the measuring signal.

• Medium selection:

The sensor has different characteristics that can be selected via the [MEdI] parameter. Note: For all

media listed in the "Note on media" (Ò data sheet), only the repeatability specified in the data

sheet applies.

• Deposits:

Deposits lead to incorrect measurements of the sensor due to their insulating effect. If there is a

risk of biological or additive deposits, refer to the maintenance recommendation in the

"Maintenance, repair and disposal" section.
