8. Operation
In order to initialise the bistable switching function, it is essential
that the float activates the contact once in each direction.
Adjustment of limit-values
The switch-point can be adjusted to the desired levels by using both red sliders
as reference points.
Reference edge for falling flow
: bottom-edge, switch housing
Reference edge for rising flow
: approx. 5 mm above the bottom-edge of switch
housing.
Slide the switch housing up or down until the reference edge coincides with the
desired switch-point scale reading.
Hysteresis
Hysteresis is the difference between the level at which “switch-on” occurs during
rising flow and the level at which “switch-off” occurs during decreasing flow. The
hysteresis is approximately 5 mm on the float range.
Overranging
With non-pulsating flow, the maximum flow rate can be exceeded. Only an
increase in pressure loss will result (max. permissible operating pressure must
not be exceeded!)
9. Maintenance
If the medium to be measured is clean, the series KSK is virtually maintenance-
free. If deposits form on the inner housing or parts, periodic cleaning of the unit is
recommended. Remove the units from the piping with a suitable tool; clean the
flow meter with a suitable cleaning agent or make use of an ultrasonic bath.
