5.1.8 General Alignment
The MaxiMet anemometer should be set to point north (or to another known reference direction), using
the north pointers, which are identified on the instrument figure on page 8.
If the MaxiMet Compass output is enabled by using MetSet (Report page, COMPASSH setting) then a direct
Magnetic North compass reading can be used to set MaxiMet north markers to north.
Otherwise MaxiMet need not be aligned precisely if the Compass Corrected Direction (CDIR) readings are
to be used.
MaxiMet has a tilt sensor output that can assist with levelling the unit.
5.1.9 Mounting Tube e.g. Gill Part 1405-30-056.
A tube 1.75 inches (44.45mm) outside diameter x 3mm wall thickness is recommended (see figures in para
5.1.11).
Note: It is important that the correct diameter tube is used to prevent damage to the MaxiMet lower
moulding when tightening the screws.
The support tube requires three 3 equally spaced holes, tapped M5, 7.5mm from the top of the tube. Pass
the cable (fitted with the 9-way Clipper plug) through the tube.
An optional 500mm long x 44.45 mm outer diameter x 3mm thick aluminium mounting tube pre-drilled
with equally spaced tapped holes is available from Gill Instruments (Part No. 1405-30-056).
Note: The customer must fit appropriate strain relief to the cable.
Connect the plug by twisting it whilst pushing it gently into the socket on the MaxiMet. When it locates,
twist the outer sleeve clockwise to connect and lock the plug.
Fix the MaxiMet to the tube using the 3 stainless steel screws provided. (Maximum mounting screw torque
1.5Nm for Aluminium tubes and 3Nm for Stainless Steel tubes).
For hostile environments, you should select a material suitable for the intended environment – for
example, stainless steel 316 for marine use.
For non-hostile environments an aluminium tube can be used.
