Abstract

A device and method to automatically switch referral matrices in a meter ( 120 ) to identify an unknown material circulating in a process application ( 900 ) and determine the material concentration, whether it may be a cleaning material or a process material. The present invention utilizes a measured line density and line temperature of the material along with a reference temperature to calculate a reference density. Using the reference temperature and reference density, a concentration percentage of the material may be determined.
