LN loss from Germanium Detectors

["Gary H. Kramer" <gkramer@hpb.hwc.ca>]

Greetings

I want to measure the rate of loss of LN from the Dewars attached to our 
Germanium detectors by looking at the gas flow from the vent tube of the 
dewar.

Does anyone know of a source for sensitive gas flow meters?
