This webinar covers some of the basics of how flow is typically measured at an NPDES discharge point. The information is applicable to the discharge from wastewater treatment plants or from industrial dischargers. The webinar also covers guidance on how various open and closed channel flow measurement devices function, how they are calibrated, and their respective applications. An onsite demonstration/inspection was conducted on a parshall flume. This demonstration included measuring the physical characteristics of the primary device and installing, operating, and evaluating the accuracy of the facility’s secondary device.
