3.8. Valmet MCA-F Sensor Deflector Plate
Installation Guide
If the flow contains pieces of string, lumps, etc., the
Valmet MCA must be protected with a special deflector
plate. Install the deflector plate at a distance of 170 mm
before the sensor on a process unit welded in line with
the sensor. After you install the process unit, position
the deflector plate such that its lag side is toward the
sensor.
Select the process unit according to the sensor ma-
terial and the diameter of the pipe (see Technical spe-
cifications). Select the deflector plate according to the
material of the sensor material (see Technical specific-
ations).
Installing the deflector plate:
– Install the process coupling as instructed in ch. 3.5.
– Check that the sealing ring is in the groove of the
flange.
– Set the deflector plate into the process coupling such
that the plate curves toward the sensor.
– Put the mounting clamps, screws and nuts into place
and tighten to a finger tightness.
– Point the plate toward the sensor with e.g. a monkey
wrench.
– Tighten the mounting clamp screws.
