5. Operating Principle
The KOBOLD flow monitor FPS ope rates according to the proven paddle bellows
principle. The flowing medium acts on the paddle thus actuating a microswitch.
Switching point can be freely adjusted and t he device mated to different nominal
pipe sizes by means of the replaceable paddle in conjunction with the additional
adjustment features. The electrical device section is separated hermetically from
the process fluid by means of a bellows.
The special version of the flow monitor has been specially designed for minimum
switching values. See table for s witching values. The devices can be installed in
any position.
6. Mechanical Connection
Before installation
Please ensure whether the actual flow matches th e switching range of the
instrument
Please ensure whether the allowable maximum operating pr essu r e an d
operating temperature of the instruments will not be exceeded.
Please ensure whether a straight r un o f 5 x pipe diameters at inlet and outlet is
being observed.
Installation
Select the paddle to suit the
pipe internal diameter. To
ensure stability the shorter
paddle should always be left
on. Make sure that the paddle
can move freely in the pipeline
and that it does not stick to the
pipe wall.
Using sealing tape screw the flow monitor into a T piece according to DIN 2950
with 1“ outlet. The arrow on the housing must point in th e direction of flow.
The unit can be fitted in any position. If the unit is installed in a vertical pipe the
weight of the paddle and the lever must be compensated with the range screw.
This leads to changes in switching values (see Sec. Setting The Limit Contact).
A suitable filter must be connected upstre am f or soile d med ia. This applies
especially to fibrous soiling.

7. Electrical Connection
Make sure that the voltage and current value s in your plant do not exceed the
respective voltage and current values specified for the flow monitor.
Make sure that the electrical supply lines are d e-e nergized.
Remove the flow monitor housing by undoing the four scr ews.
Connect the flow monitor as shown in the wiring diagr am.
Red-white opens if the flow rate drops to the set value . Red-blue close
simultaneously and can be used as a signal contact
The unit is ready for operation when you have connected
your external devices to the limit contact.
8. Setting the Limit Contact
The units are delivered with an adjustable microswitch.
The contact is a changeover con tact that can be wired for use as a N/O or N/C
contact.
The units are set to the minimum switch-off value at th e f act or y.
The switch-off value can be set to a higher value by rotating the range screw
clockwise.

9. Maintenance
In cases where the flow medium is uncontaminated, the FPS will remain
maintenance-free. Large dirt part icles ca n block th e be am.
Depending on the amount of dirt pres ent in the medium, we recommend that the
Instrument is checked at regular intervals.
