9 Installing the sensor
9.2.2 Installing the sensor
Observe the flow direction indicated
on the top of the meter or on the
shaft. Make sure it matches the flow
direction of the compressed air or
gas.
1. Close the ball valve
2. Rotate the connection head to
make its connection thread cover
the sensor probe tip completely.
3. Underlay the copper gasket
sealing ring at the thread of the
connector head.
4. Tighten the connection head to
the ball valve. During the process,
move the shaft to make the arrows
shown on the top of the sensor
head point to the flow direction in
the pipe.
5. Open the ball valve.
6. Move the flow sensor slightly to
the calculated insertion depth by
means of the scale on the shaft.
7. Tighten the locking nut by hand
so that the flow sensor cannot be
moved by the pressure in the pipe.
NOTE: The locking nut is a hex nut
with the adjacent edge angle of 60
degrees. See the figure on the next
page.
