4. Regulation Use
Any use of the Flow Meter, model: KSV, which exceeds the manufacturer’s
specifications, may invalidate its warranty. Therefore, any resulting damage is not
the responsibility of the manufacturer. The user assumes all risk for such usage.
5. Operating Principle
The KSV flow meter for liquids or air operates on the suspended float principle.
The direction of flow is from bottom to top, and the installation position is vertical.
The indication point is the upper edge of the ball.
The device has been designed as a simple and thus economical measuring
system. The optional needle valve allows economical control. The device has
been designed for panel mounting.
6. Mechanical Connection
Before Installation:
 Remove all transportation safety locks and ensure that no packing material
remains within the unit.
 Be sure that the maximum allowable operating pressure and temperature is
not exceeded (see Technical Data).
 Install the flow meter in the piping system, making certain the instrument is
under no mechanical stress/tension (install support bracing if necessary).
 Protect the measuring tube from external damage.
 Avoid pressure peaks in the measuring tube, e.g. from sudden surges or
stoppage of flow.
 If possible, immediately after making mechanical connections, check whether
the connections are properly sealed with no evidence of leakage.
Detailed information regarding installation of float flow meters is
available in VDI/VDE guidelines 3513.
Warning! During measuring range excesses of more than 20 % is to
be counted on bearing damages and substantial measuring errors.
