Praxair has introduced a new, patented remote monitoring system developed for worldwide monitoring of cryogenic containers.

The patented monitoring system will detect liquid level, temperature and pressure data in both the insulating layer of nitrogen and helium inner vessel to ensure optimal cryogenic properties during shipment. This new technology allows remote readout and potential control of the container\\$quot;s arrival conditions during various stages of the transport process. It directly benefits customers because it ensures reliability at the end of the delivery process.

"We are now monitoring our high-value helium containers during worldwide transport, utilizing Global Positioning System (GPS) coordinates that verify timely shipments and improve container utilization," said Tom Bulin, global helium supply manager.

"This one-of-a-kind system also gives us flexibility to monitor and proactively control helium product while in transit, increasing reliability of supply and proper helium arrival conditions for our customers."

Container information is stored in an on-board computer database that transmits the data via wireless communication modems such as cellular or satellite back to logistics planners on a regular basis. As a result, time-dated information can be used to accurately determine the condition of the liquid helium throughout the length of the trip. In addition, an accelerometer is used to monitor the high G-force loads, which can determine when damage occurred to the container. Praxair is also working on an applications software package, which would be capable of combining and delivering various data reports as one total business solution.
