7.1.2 Venting during operation
The assembly is designed in such a way that disruptive air bubbles cannot accumulate in
the assembly under normal operating conditions. Any gas bubbles that form are usually
discharged by the flow of liquid. If, however, manual venting is necessary, this can be done
in two ways:
• Increase the liquid flow for a short time in order to discharge the gas bubbles (pay
attention to the operation of the valves). Then reset to the original flow rate.
• Loosen the sensor carefully and to the smallest extent possible so that the air in the
sensor module can be displaced by liquid. Then retighten the sensor.
