The FCML 412-M12 has a marking on its shaft for optimum installation in the
flow-through vessel D 19.
The position in the flow through vessel has a considerable effect
on the approach flow and, hence, the measuring function of the
sensor. Therefore carefully position the sensor as described
below.
Proceed as follows to install the sensor:
1.
Connect the ADA CL/IDS adapter to the M12 flange plug and screw
it tight.
2.
Push the coupling ring of the flow-through vessel loosely onto the
sensor.
3.
Insert the sensor with the coupling ring in the flow-through vessel.
