2.2 Functional description

The ow switch works by the calorimetric principle and is used to convert the ow rate into an electric signal. The

instrument shows the ow rate in per cent on the digital display.

Optionally, the instrument measures the medium temperature.

The instrument can output up to 2 output signals as parameterised.

■

Switching signal for ow limit values

■

Switching signal for temperature limit values

■

Switching signal for diagnostic function

3. Safety

The ow switch is used for monitoring ow losses and dry run. With analogue signal the ow switch should only be

used as a trend indicator, in order to monitor process changes, such as lter blocking.

Only use the ow switch in applications that lie within its technical performance limits.

→ For performance limits see chapter 9 “Specications”.

Refrain from unauthorised modications to the ow switch.

Any use beyond or dierent to the intended use is considered as improper use.

The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.

3.3 Personnelqualication

Skilled personnel

Skilled personnel, authorised by the operator, are understood to be personnel who, based on their technical training,

knowledge of measurement and control technology and on their experience and knowledge of country-specic regula-

tions, current standards and directives, are capable of carrying out the work described and independently recognising

potential hazards.

Special operating conditions require further appropriate knowledge, e.g. of aggressive media.

4. Transport, packaging and storage

4.1 Transport

Check the ow switch for any damage that may have been caused by transport.

Obvious damage must be reported immediately.

4.2 Packaging and storage

Do not remove packaging until just before mounting.

Keep the packaging as it will provide optimum protection during transport (e.g. change in installation site, sending for

repair).

Permissible conditions at the place of storage:

■

Storage temperature: -20 ... +80 °C

■

Humidity: 45 ... 75 % relative humidity (no condensation)

Avoid exposure to the following factors:

■

Direct sunlight or proximity to hot objects

■

Mechanical vibration, mechanical shock (putting it down hard)

■

Soot, vapour, dust and corrosive gases

■

Humid or wet environment

■

Hazardous environments, ammable atmospheres
