Chapter 2 Installation
Positioning the sensor rod
(When sensor rod is longer than the internal diameter of the pipe)
The sensor head must be located in the centre of the pipe (see Fig. B of the following diagram)
The simplest way to guarantee this is to assemble the 3/4" thread or the flange, and then push the sensor
into the pipe up to the stop. Then, pull the sensor back by exactly one half of the nominal diameter of the
pipe (minus 6mm) and now fix it in position by means of the cutting ring connection (max. 1¼ turns).
Where a stainless steel cutting ring is used, the sensor can be positioned only once!
The sensor rod must be fixed securely. Where the pipe is subjected to high pressure, there is a risk of the
sensor being ejected as far as the clamping ring in the manner of a projectile and thereby endangering
personnel.
(When sensor rod is shorter than the internal diameter of the pipe)
In the case of larger pipe diameters, proceed as shown in Fig. A of the following diagram.
The sensor is pulled back to the reducing pipe nipple. Mark the sensor rod at a distance of
"DI/2 + B - N"
DI/2
= half internal diameter of pipe
B
= Inner wall of pipe up to reference edge
Look up dimension “B“ corresponding to the variant of mounting in the instructions on
page 13, page 14, or page 15.
N
= KL + S - 6 mm KL = Screw fitting, S = Sensor head
Please choose dimension “N“ from the table on page 17.
Push the sensor into the clamped connection up to this mark (see Fig. B of the following diagram) and fix
it in position by means of the cutting ring connection.
Where a stainless steel cutting ring is used, the sensor can be positioned only once!
The sensor rod must be fixed securely. Where the pipe is subjected to high pressure, there is a risk of the
sensor being ejected as far as the clamping ring in the manner of a projectile and thereby endangering
personnel.
