Automatic Liquid Nitrogen Fill Mechanism
The mechanism is based on a vapor pressure switch (containing argon gas)
and a timer box. Every 6 hours the filling is started, and stopped
when the LN2 reservoir is full. The filling time is limited to 10 minutes
in oder to avoid damage in case of sensor damage. If the sensor has a leak
the switch would indicate "vessel full", which is also a safety feature.
