f) It may be advisable to erect a lifting beam above the proposed location of the analyser to enable
easy ingress and egress of the probe using a hoist. The picture below shows an 'I' beam acting as a
lifting point for a hoist to carry the load of the probe and transceiver.
Figure 12 : Beam Lifting Point
The measurement tube is supplied fully assembled but without the transceiver unit fitted.
The tube is now ready for insertion into the duct or stack, through the previously fitted stub-pipe and site
mounting-flange. Note that when finally positioned the diffuser section of the tube should be rotated so that the
two rows of diffuser disks are positioned as shown in Figure 2 in relation to the general gas flow. As these are
out of sight when the tube is inserted, mark one end of the tube so that the correct orientation can be achieved
after installation. When installing the measurement tube, ensure that the pressure sensor is mounted above the
centreline of the probe
Figure 13 : Position of Pressure Sensor
Use the mark previously made to rotate the tube so that the diffusion disks are oriented to the
general gas flow as shown in Figure 2. This is important!
