Special mounting instructions
Hygienic compatibility
If installing in hygienic applications:
• Observe the instructions in the "Certificates and approvals/hygienic compatibility" section
• Ensure that liquid cannot accumulate on the outside of the measuring device.
• If the measuring device is installed horizontally, align the connection socket for the
connecting so it is pointing upwards.
• Select the orientation in such a way that the measuring device is self-draining when
installed. Installation with an angle of inclination >3° is recommended for this purpose.

WARNING
Danger due to improper process sealing
‣
Only use the seals provided by Hauser. Replacement seals can be ordered as
‣
Use clean, undamaged seals only.
‣
Firmly tighten the screws of the process connections. The process connection forms a
metal connection with the sensor, which ensures a defined compression of the seal.
‣
Depending on the application the seals should be replaced periodically, particularly if
gasket seals are used (aseptic version). The interval between changes depends on the
frequency of the cleaning cycles, the cleaning temperature and the medium
temperature. Replacement seals can be ordered as an accessory → 78.
Mounting the sensor with the threaded adapter in the pipe
‣
Mount the sensor in the pipe in full compliance with the mounting conditions → 20.
Welding the sensor with the welding socket into the pipe
1. Tack-weld the process connection to secure it in the pipe.
2. Release the screws on the process connections and remove the sensor, along with the
seal, from the pipe.
3. Weld the process connection into the pipe.
4. Mount the sensor, along with the seals, back on the process connections. Ensure that
all the connection parts are clean and the vent groove on the process connection is
located on the underside of the transmitter.
5. Check whether the process connections and seals are centered when mounted.
6. Tighten the screws in diagonally opposite sequence with a torque of 7 Nm (5.2 lbf ft).
