2.1.2 Electrical hazards
●There is an immediate danger of fatal injury from electric
shock when touching live parts. Damage to the insulation or
individual components can be lethal.
●Only have qualified electricians carry out electrical work on
the product.
●In case of damage to live components, switch off the voltage
supply immediately and arrange for repair.
●Switch off the supply voltage before working on electrical sys-
tem parts. Discharge residual voltage.
●Never bridge electrical fuses. Do not disable fuses. Use the
correct current ratings when replacing fuses.
●Keep moisture away from live parts. Moisture can cause
short-circuits.
2.1.3 Groups of persons requiring protection
●This product is not designed to be used by persons (including

3 Product description
3.1 Intended use
●The filling level indicator GENO-Multi Niveau is used in the in-
dustrial and commercial sector to indicate the filling level of
permeate/pure water tanks.
●The filling level indicator GENO-Multi Niveau is used in the
swimming pool sector to indicate the filling level of raw water
tanks.
3.1.1 Application limits
When using a tank from another manufacturer, make sure that the
tank can be filled smoothly and steadily, so that the filling level
does not fluctuate too much due to wave action.
●When using a suitable level probe or a suitable pressure
transducer, a filling height in the range of 100 –1000 cm can
be indicated as well.
●Only tanks with linearly increasing filling volume can be evalu-
ated.
●Cylindrical tanks lying in a horizontal position as well as
spherical or conical tanks cannot be evaluated.
3.1.2 Foreseeable misuse
●Use in sea or salt water pools

BA_712940-inter_175_GENO-Multi Niveau.docx
3.3 Functional description
The filling level indicator GENO-Multi Niveau is designed to meas-
ure and display the filling level in permeate/pure water or raw water
tanks.
Membrane systems, pressure booster systems or pool water sys-
tems and make-up water feed systems can be controlled via pro-
grammable switching contacts.
Pressure measurement
By means of a level probe at the bottom of the tank, the pressure
generated by the water column is registered and emitted as a
4 –20 mA signal.
The filling level indicator GENO-Multi Niveau converts the pressure
signal into a filling height (cm), a filling level (%) or a filling volume
(m³).
