Abstract
A sight flow indicator having a viewing window for monitoring liquid flowing therethrough is disclosed. The flow indicator is configured to disentrain gas and particulate from a portion of the fluid. The flow indicator is also configured to reduce the velocity of fluid flowing therethrough. The portion of the fluid from which gas and particulate has been disentrained is diverted from the main flow stream, past the viewing window. The relatively clean liquid sample flowing past the viewing window lends itself to relatively accurate optical analysis using, compared to the bulk fluid flowing through the flow indicator. The flow indicator is well-suited for use with a spectrometer or other optical analyzer.
