Abstract
A flow cell system for use with a nephelometer (i.e., turbidimeter) to measure the turbidity of a liquid (e.g., water). The flow cell includes a transparent sample cell, an inlet port on the upper end of the cell, an outlet port on the upper end of the cell and another outlet port on the lower end of the cell. The upper outlet port collects and expels air bubbles and particles that tend to float in the sample. The lower outlet port collects and discharges settled solids. Measurement can be made on a dynamic (flowing) sample or a portion of the sample may be measured under static (non-flowing) conditions.
