driver, a magnet with several poles is set into rotation, which is able to activate a magnetically switched

contact through the lid of the housing. Every revolution of the nutating disc is assigned to a constant volume

5.3 Safety measures when handling the battery

NOTICE

Lithium batteries represent a safe and reliable energy source when used properly. However, these

potential consequences may occur if they are used incorrectly or misused:

• Theleakageofbatteryuidor

• the escape of gas or, in extreme circumstances,

• areand/or

• explosion.

Do not reverse the polarity of the battery. Note the + and – symbols on the battery and device.

If batteries are inserted the wrong way they can be short-circuited or charged with the potential conse-

quences described above.

Do not short-circuit the battery.

If the positive pole (+) of a battery is connected directly to the negative pole (–), a short-circuit may occur with

the potential consequence described above. It is best to store unused batteries in their original packaging.

Do not charge batteries

Trying to charge a non-rechargeable battery may lead to it overheating with the potential consequences

described above.

Do not over-discharge batteries

If batteries are over-discharged on an external power supply, the battery voltage is dragged below the

value for which they were designed with the potential consequences described above.

Remove and dispose of depleted batteries immediately

Although lithium batteries are exceptionally leak-proof, it is more likely for a leak to occur with a depleted

battery rather than with an unused battery.

Do not overheat batteries

Electrolyte may be released if a battery overheats. Separators may also be impaired with the potential

consequences described above.

Do not open batteries

Ifabatterycellisopened,thecomponentsmaycauseaninjuryorre.

Do not damage batteries

Lithium batteries should not be crushed, drilled or damaged in any other way as this may lead to the

potential consequences described above.

Do not throw batteries into a re

Ifbatteriesarethrownintoare,thismayleadtothepotentialconsequencesdescribedabove.Only

dispose of batteries by burning them in an incinerator approved for this purpose.

Do not bring the content of lithium batteries into contact with water

This may lead to the formation of hydrogen and lead to the potential consequences described above.

Store batteries out of the reach of children

Store batteries out of reach of children, especially if they could be swallowed. Seek immediate medical

advice if a battery is swallowed.

5.4 Safety measures when handling the touch screen

NOTICE

The display may become illegible due to pressure marks and scratches.

►Press the touch screen lightly and do not touch it with sharp objects.

! WARNING

The ow meter system may uncontrolled restart.

►Shutdowntheowmetertocleanthetouchscreen.

NOTICE

Detergents may attack the surface of the touch screen.

►Do not use solvents for cleaning.

►Clean the touch screen with a soft damp cloth.

►If necessary, use pure alcohol (observe the safety data sheet)

5.5 Prevention of obvious misapplications (examples)

• Donotconnecttheoperatingunitwithotherelectronicdevicesiftheirusabilityisnotconrmedbythe

manufacturer.

• Do not use operating units BE10 and BE10V neither in explosive hazard area nor with electric connection

in explosive hazard area.
