Title Author Date
Performance Comparison of Flexible Detector Designs Ronan Measurements 02/06/2008
The purpose of this paper is to present test results of recent measurements on a scintillating fill fluid (i.e., liquid scintillator filled) detector and a scintillating fiber bundle detector designs, and explain the observed differences in efficiency. In our measurements we observe an improvement of factor of 2.4 in light output for a fill fluid detector compared to scintillating fiber bundle detector of the same diameter and length. 
Unraveling the complexities of level detection Turck 05/23/2006
Sensing options enable users to choose the sensor most appropriate per application. However, making this choice is not often easy. This paper helps unravel the complexities and differences between sensor types and applications in which they are used. 
Flow, Level and Environmental Handbook Omega Engineering 06/27/2005
Features a variety of meters and controllers, portable, handheld and laboratory instruments measuring air, water, conductivity, dissolved oxygen, flow, high viscosity liquids, and pH.
