bulk solids handling Journal White Paper Can you go with the Flow? Solids Flowmeters for Industrial Applications Solids flowmeters are an interesting solution to indicate flow rates in pipes and chutes. “Interesting” because they are only moderately accurate, costly, require a lot of tuning after installation and are usually only as good as the whole process around them. Nevertheless, the technology exists…read more
