Less cryogen handling reduces costs and improves safety!

AMI's extensive experience encompasses the unique requirements for accurately measuring and efficiently controlling cryogenic liquid levels, primarily (but not limited to) nitrogen in unattended auto-fill systems for both laboratory and heavier-duty industrial applications. Depending on the complexity, these systems incorporate either our Model 186 or Model 286 Liquid Level Controller and associated Liquid Level Sensors into a safe and reliable level control system. Dewar sizes range from "standard" 5 to 50 liters, to the less than 0.25 liter dewars used in IR/CCD detector systems.

Unattended Auto-fill applications

These are just a few of the many unattended auto-fill applications for systems that need uninterrupted LN2 temperature environments:

Crystallography
CCD and HgCdTe Detectors
X-ray and Gamma-ray spectro-scopy systems
Biological sample or single-crystal storage
Astronomy
Florescence and Chemilumine-scence spectroscopy

Gravity-Feed

Gravity-feed systems are an AMI innovation applied in situations where the target dewar must be kept contuously full. In these applications, the source dewar is mounted above the target dewar and is the object of the autofill function.
