3.5.2 Installation of weld-on versions
For mounting sensors with weld-on connections, please follow the procedure as follows:
• Mount the sensor completely in the pipeline and spot the weld-on connections to the pipe. This
is necessary to align the mounting bores of the flange.
• Remove the sensor body and the gaskets from the adapters by loosen the screws.
• Weld the adapters completely to the pipe.
• When the pipe is cold again, reinstall the gasket and mount the sensor.
