Figure 30—Example of a Pitot Tube
Fitting a pitot tube to the analyzer:
1) It is important to seat the pitot tube into the monitoring point with the tip facing
into the gas flow. The pitot tube should also be housed half way down the
monitoring pipe.
2) Make sure that the sample tubing attached to the pitot tube fits correctly.
3) Attach the sample tube from the top connection of the pitot tube to the ‘blue port’
(the differential port) on the analyzer making sure that the gas port connector
secure into place.
4) Attach the sample tube from the side of the pitot tube to the ‘white port’ (inlet
port/static pressure port) on the analyzer making sure that the gas port
connector secures into place.
5) House the pitot gland correctly onto the monitoring point.
6) When taking a gas reading and flow measurement follow the instruction as
displayed on the front of the instrument.
Note: Please refer to the following section for a diagram showing how to fit
the tubing to the pitot tube.
