Pipes
The measuring device must be professionally installed, and the following points must
be observed:
• Weld pipes professionally.
• Use seals of the correct size.
• Align flanges and seals correctly.
• Remove protection cap from sensing element.
• Following installation, the pipe must be free from dirt and particles in order to avoid
damage to the sensors.
• For further information → ISO standard 14511.
Sensor selection and arrangement
The minimum length of the sensor can be determined using the Endress+Hauser
Applicator program (version 10.00 or higher) or with the calculation formula below.
The minimum length of the sensor is determined by the necessary insertion depth. The
calculated necessary insertion depth must be within the adjusting range of the selected
insertion version.
Insertion depth
The minimum length of the insertion version can be determined using the Endress+Hauser
Applicator program or with the calculation formula below. The calculated necessary
insertion depth must be within the adjusting range of the selected insertion version.
NOTICE
Metal ferrules undergo plastic deformation during the initial installation.
As a result the insertion depth is fixed after initial installation and the ferrules can no
longer be replaced.
‣
Pay attention to information on preconditions and on determining the insertion depth.
‣
Check the insertion depth closely before tightening the ferrules.

Calculating the insertion depth
Insertion depth = (0.3⋅ A) + B + (C1 + C2)
The insertion depth must be at least 100mm.
