Flow meter selection
Thread Content
Flow measurement is required on-site; it’s a DN40 pipeline, and the medium in question is quite corrosive. The conductivity of this medium was considered acceptable earlier, so fluorinated-coated electromagnetic flowmeters were used at that time. But in practice, when there is little water present and only the medium itself is involved, the conductivity is very low, making it difficult to carry out measurements. I’m not sure which type of flowmeter would be better in such cases – how about external ultrasonic flowmeters? It’s about selecting flow meters that are highly corrosive and non-conductive
The medium can be mentioned so that it can be analyzed. At the very least, use mass flow accumulation.
As for how low the conductivity can be, just ask the manufacturer
Be practical rather than theoretical; analyzing things here based on imagination?
