Wastewater Effluent Flowmeter that measures flow from two 90 degree V-Notch weirs at the effluent of a wastewater treatment plant. The system uses a Nivelco Ultrasonic Level Transmitter / Flow Meter – Nivelco EasyTREK SPA-38N4. The effluent flow meter provides a 4-20 mA signal to provide flowpacing to the effluent sampler. The effluent flowmeter signal is also sent and further processed in the Nivelco MultiCONT process controller where the flow and totalizers are displayed. The MultiCONT can be expanded to offer additional signal outputs, relays and communications for other equipment. Effluent flow meters are also called discharge flow meters or effluent meters.
