Function And Features; Installation - IFM Electronic efector300 Montageanleitung

Function and features

The flow monitor monitors liquid media. It senses whether there is a
preset flow and provides a switching signal.
The switch point can be set: minimum value (< 10) - 10 - 15 - 20 ...
55 - 60 - maximum value (> 60).
This value is valid for water and installation in pipes 4". It changes with other
media/other pipe diameters.

Installation

The sensor tip must be completely immersed in the medium.
•
In the case of horizontal pipes mount the unit from the side, if possible (fig.
1).
When the unit is to be mounted at the bottom of the pipe, it should be free
from deposits. When the unit is to be mounted at the top of the pipe, it
should be completely filled with the medium to be monitored.
• In the case of vertical pipes mount the unit in a place where the medium
flows upwards (fig. 2).
Use only a correctly-sized spanner (or torque wrench) to fasten the unit.
Tightening torque max. 100 Nm (with stainless steel adapter) or ANSI B1.20.1.

To avoid malfunction a minimum
distance between the flow mon-
itor and bends, valves, changes
in cross-section or such like must
be observed:
• Min. 5 x pipe diameter
upstream (A),
• min. 3 x pipe diameter down-
stream (B).
