Level Monitor is a piece of software written in LabVIEW designed to display, record and graph the helium level of the dewar attached to the compressor in LG12. See HeliumLiquefierMonitoringSoftware for details on set up and how to run this program.


  • The vi records the level of the dewar, in cm and L, as well as the rate, in cm/h and L/day. The log files are automatically created when the program runs and are kept in C:\Liquefier Logs. A new log will be created on a weekly basis if the vi is left running.
  • The vi displays graphs of the helium level and liquefaction rate.
  • The vi can recall the set up of the level monitor.
  • The vi uses the LabView server to maintain a website showing the graphs.
