Whether Half-Empty Or Half Full, Krohne Helps Back River Accurately Measure Flow

Some people look at the glass half full, some look at it as half empty.  Neither approach is inherently bad, it's just two different ways of looking at things.

However, if a pipe in a wastewater treatment plant is only 50% filled, it doesn't matter whether you call it half full or half empty.  When it comes to measuring the liquid in that pipe, either way presents a significant problem.  The dilemma comes down to one undisputed truth: few instruments can accurately measure the level of flow in a pipe that is half full - or less.

Primnath Rambissoon, instrumentation supervisor at the Back River Wastewater Treatment Plant in Baltimore, was all too familiar with this issue. 

"We had a process in the plant that had been shut down for quite awhile, and when we restarted it, we had problems taking the measurement in that pipe," said Rambissoon, who is also in charge of the plant's remote pumping stations and remote media stations.  "It was an application where the flow rate was very low and the pipe wasn’t completely full.  Unfortunately, the flowmeter we were using was simply unable to measure flow when it was that low."
