Here’s the fact. Demineralised water is not good for you. Measuring demin – what’s so hard? Well, demineralised water is just that – it’s water, which has probably been treated, to remove the natural minerals that occur in nature. The lack of these additives leaves the pure water actively looking for minerals to replace them. … Read more
As with most flowmeter selection processes the choice of volumetric or mass is decided by just a couple of criteria.
