3 Installation examples
1, 2 Perpendicular to flow direction, installed at a minimum angle of 3° to ensure self-draining
3 On elbows
4 Inclined installation in pipes with a small nominal diameter
U Immersion length
In the case of pipes with a small nominal diameter, it is advisable for the tip of the thermometer
to project well into the process so that it extends past the pipe axis. Installation at an angle (4)
could be another solution. When determining the immersion length or installation depth all the
parameters of the thermometer and of the medium to be measured must be taken into account
(e.g. flow velocity, process pressure).
The use of iTHERM QuickSens inserts is recommended for immersion lengths U <
70 mm (2.75 in).
