2. Note
Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
The devices are only to be used, maintained and serviced by persons familiar
with these operating instructions and in accordance with local regulations
applying to Health & Safety and prevention of accidents.
By usage in machines, the measuring unit should be used only when the
machines fulfil the EC-machine guidelines.
3. Regulation Use
The Model PPS-.. is installed for the purposes of monitoring flow throughputs of
liquids in nominal pipe sizes greater than NW 32. The paddle switch is available
with a factory set limit switch (N/O or N/C). It is suitable for low viscosity fluids
which have no effects on the instrument materials used. The flow throughput
switching point is determined by the length of the paddle. During installation the
paddle length may be reduced by cutting to adjust the set point.
4. Operating Principle
Media flowing in any direction moves the paddle,
which rotates an eccentric, which in turn raises an
assembly within the unit. The assembly has a
permanent magnet mounted within it. This enables
the magnet to activate a hermetically sealed reed
switch. The signal from the reed switch can be used
to trigger an alarm or indicator. With the appropriate
relay, it is possible to automatically control pumps,
motors or valves.
