Accurate partially-filled pipe measurement is essential when dealing with variable stormwater flows or over-sized community systems built for future growth. In Europe, new stormwater regulations requiring treatment before release are driving a change in measurement that will likely be seen in the U.S. in the not-too-distant future.
There are a variety of ways to measure flow in a partially-filled pipe including laser or radar where the meter tries to map the half-pipe. There’s also a separate practice where a level device is inserted through the top of the pipe and an area velocity meter is installed in the bottom of the pipe.
The TidalFlux from KROHNE measures from ten percent of level all the way up to filled. In this exclusive Water Online Radio interview, Rich Lowrie, Water and Wastewater Industry Manager for KROHNE, explains how the TidalFlux works and what some of the specific applications for partially-filled pipe measurement are.
“We have 21 of these meters installed around Pottsville, PA,” explains Lowrie, “It’s all for flood diversion. This town has had four 100-year flood events in a seven year period. Every time it blew out their plant and they were fined heavily. So they built diversion chambers and today, they use our meters to divert the flow when it gets high enough.”
