Hot Tap Sensor Installation - Teledyne ADFM Pro20 Installation And Operation Manual

2.7 Hot Tap Sensor
Installation
Early HTI
Figure 2-42 Early and current versions of the HTI sensor
Recent changes have been made to the design of the Hot Tap
Insertion (HTI) sensor. The two versions have slightly different
dimensions and hardware. Operation is exactly the same for
both.
The two versions are most distinguishable from one another by
the appearance of the box at the head of the shaft. See
Figure 2-42, below. If your sensor has the smaller, metal box on
the left, follow the instructions in Section 2.8 Insertion: Early
Version HTI. If your sensor has the larger, molded box on the
right, follow the instructions in Section 2.9 Insertion: Current
HTI.
Current HTI
Never loosen any hardware on the Hot Tap sensor when the
pipe is pressurized. Pressure within the pipe can force the
shaft to come out of the pipe, causing grave injury to
anyone nearby.
