Version HTI
Tools and supplies
Dimensional requirements
These instructions refer to Figure 2-44 on the following page.
The preferred locations for sensor installation in a horizontal
pipe are between the clock positions 1 and 5, and 7 and 11, as
shown in Figure 2-44. Installation at the top and bottom of the
pipe should be avoided due to the possibility of trapped air or
sedimentation. The sensor may be installed at any position in a
vertical pipe, provided the stream is flowing upward.
For all other variations in position or flow, contact Teledyne Isco
for assistance.
Installation of the Hot Tap requires the following user-provided
tools and supplies:
• Tapping saddle, thread-o-let, or spool piece
• 2" NPT Corporation stop or ball valve
9
• / " hex screwdriver
64
• Pipe wrench
• PTFE pipe thread tape
• Optional cable conduit (min. 2" dia.)
The standard length of the Hot Tap sensor cable is 50 ft (15m). A
custom-length cable can be up to 100 ft (30m). If conduit is used,
a minimum diameter of 2 in. is required. Minimum bend radius
for the cable is 6 in.
When determining the installation location, consider the
minimum clearance required for installation and removal of the
sensor from the pipe. The minimum clearance required is found
by calculating the dimension C.
For the standard length sensor, the distance from the top of the
valve to the inner pipe wall (D) must not exceed 15" in order to
have an insertion depth of up to 1
Note
Typical insertion depth is usually between
1
/ in. However, installations in pipes where buildup of grease
2
or debris is expected, deeper insertion will ensure unimpaired
flow readings.
