Semi-automatic dewar switchover systems provide a continuous, uninterrupted flow of liquid nitrogen to the use point. 

When the primary source is empty, semi-automatic switchover to a standby, full, secondary supply is easy, thus eliminating outages. When a dewar is empty, the user will be informed. Switchover will be performed by pushing a button on the HMI of the electrical cabinet. 

Switchover stations require constant monitoring of the liquid nitrogen level in the storage vessels. Liquid nitrogen volume inside the vessel can be monitored by float level measurement, by digital display or by installing the container on a weighing scale.

Switchover stations are also an efficient and economical alternative to installing a bulk storage tank with extensive vacuum insulated pipelines.
