The paddle wheel of the sending unit is rota-
ted by the flow of water. The rotational
speed of the paddle wheel is measured
without contacts, and transmitted to the indi-
cating instrument.
Use a screwdriver to replace the paddle
wheel and its shaft.
Carefully lift the paddle wheel shaft upwards
to remove it from the sending unit.
Insert the new shaft into the new paddle
wheel and install shaft and wheel, again
using the screwdriver.
Check the correct installation direction when
replacing the paddle wheel. The spoon-sha-
ped leading surface of the wheel (A) must
be directed towards the pointed side of the
loop (S).
