Flow sensor SS 20.260 Page 8
SCHMIDT Technology provides a convenient calculation tool to compute
flow velocity or volume flow in pipes (circular or rectangular) for all its sen-
sor types and measuring ranges on its homepage:

Mounting in a wall
The housing has an external thread M18 x 1 (19 mm long) for direct
mounting on or in the medium separating wall. Its advantage lies in the
simplicity of installation without special accessories; however, the probe
length defines the immersion depth in this case and this method requires
access from both sides for operation.

Drill a bore in the wall with 13 … 14 mm diameter.

Carefully insert measuring probe with an attached protection sleeve
into the bore so that the mounting block of the enclosure is in contact
with the wall.

Screw on the enclosed fastening nut by hand on the medium side,
turn sensor into required position and tighten fastening nut (SW22)
while holding up the enclosure on the mounting block by means of
SW30.
Angular deviation should not be greater than

3° relative to
flow direction.

Check the set angular position carefully, for example by means of a
spirit level at the octagonal part of the sensor enclosure.

Finally, remove protective cap from sensor tip.
