Locate a suitable gland or bung on the
pipework and insert the vane anemometer,
taking care to ensure that the anemometer is
correctly orientated. The arrow on the tip of
the anemometer should be in line with the
pipe, NOT at right angles to it. When the
anemometer is as far into the gland as
possible, without opening the tap, re-check
the orientation and open the gas tap. Finally,
push the anemometer into the gland far
enough to ensure that the vane head is in
the centre of the gas pipe.
The display screen will change to show the
last retained gas velocity reading indicated
by the highlight around the velocity figure.
Now press the ‘sample’ key. The instrument will now measure the velocity of the
gas flowing through the pipework.
When the reading has stabilised, press the ‘sample’ key again to retain the reading.
This will return the highlight area around the velocity figure.
Carefully remove the vane anemometer from the gland on the gas pipe, pausing to
turn off the gas tap before removing it completely.
This completes the measurement.
Auto Turn Off
To help conserve battery life, the GFM600 instrument features an auto power off
facility. This ensures that the instrument will switch itself off after 10 minutes if no
keys are pressed.

Take great care
when inserting the
anemometer to
avoid gas leakage.
Take great care
when removing the
anemometer. In
particular, avoid
standing with your
face in direct line
with the gland
because gas can
be expelled at
great force.
