Flow meter devices are the most widely used process monitoring instruments in wastewater treatment. Careful consideration must be exercised during selection of flow meters to avoid equipment misapplication that can result in operation problems and equipment failure. It is the responsibility of the designer to select the appropriate type of flow meter device and to integrate the instrumentation design into the treatment plant design. A flow measurement system consists of a primary element and a converter device to provide flow reading. The primary element is a sensor or detector that is exposed to and affected by the rate of flow. The converter device changes the sensor reading to a usable flow reading. Because of the broad scope of the subject, the document only presents information concerning the selection and proper application of the primary element of flow meter devices. Details on design and selection of flow meter devices are in the references for this document.
