Inside diameter measurement gauges
Before the probe is installed, measurements may be performed using an adaptable diameter gauge
on a 1" insertion thread. Their use requires the appropriate clearance above the pipe.
Figure 14: View of the different components of the diameter gauge
The diameter gauge has a bleed screw to evacuate the pressure. This is useful when excessive
pressure prevents the user from bringing the gauge down to the bottom of the pipe.

Note that a gauge can be created with a personalised size and thread (please ask us). Available gauge
models and their sizes are described in detail in
