Effluent Flow Meter

The effluent flow meter is an 18-inch diameter magnetic flow meter located in the influent line from the secondary sedimentation tanks to the chlorine contact tanks. The meter utilizes the principle of electromagnetic induction to produce an AC voltage proportional to the rate of fluid flow. A signal converter transmits an analog 4-20 mA DC signal proportional to flow rate to the data logger, where the flow is recorded. The flow meter signal is also used to control the Composite Effluent Sampler in the Analyzer Room of the Chlorination Building, and to control chlorination and dechlorination.
