One of the most perplexing challenges for wastewater plant operators is the need to measure the various sources of influent. This is especially true for closed-pipe systems where the use of traditional flow devices requires intensive and expensive engineering to keep the pipe full at the point of measurement.
While conventional wisdom has been that electromagnetic flow meters (or “mag meters”) only work with full pipes, there is an emerging solution that measures flow in a less-than-full pipe. These meters, such as the KROHNE TIDALFLUX 2300 mag meter, are ideal for combined sewer overflow applications.
Rich Lowry, the water and wastewater industry manager with KROHNE, discusses improvements in partial-pipe flow metering technology in this Water Talk interview at WEFTEC 2019.
