If the display shows 100 %, this means either free water or defective
sensor.
CAUTION !

5.2 Ideal saturation level in hydraulic and lubrication systems

Since the effects of free (or emulsified) water are more harmful than those of dissolved
water, water levels should remain well below the saturation point. However, even water in
solution can cause damage. Therefore, every reasonable effort should be made to keep
saturation levels as low as possible. There is no such thing as "too little water" in hydraulic
and lubrication fluids!
Saturation level
As a guide, we recommend that saturation levels remain below 45 %
in all systems.

Assembly

6.1 General installation notes

The sensor can be installed directly in the hydraulic system via the threaded
G 3/8 A ISO 1179-2 threaded connection. For hydraulic applications the recommended
mounting position is vertical with the mechanical threaded connection pointing upwards.
When installing, ensure that the sensor is fully submerged in the fluid and that the fluid can
circulate freely around the sensor. For tank installation therefore, the sensor should be sited
only where turbulence is known to occur.
