Electromagnetic flowmeters:
Used to measure all electrically conductive liquids (> 5
µS/cm) with or without solids, e.g. water, wastewater,
sludge, slurries, pastes, acids, alkalis, juices, fruit
pulp, etc.
Used in water/wastewater, chemicals, pharmaceuticals, pulp
and paper, foodstuffs, etc. Electromagnetic flowmeters are
even robust enough to be used in mining.
Mass flow meters:
Virtually all fluids can be measured: cleaning agents and
solvents, fuels, vegetable oils, animal fats, latex,
silicon oils, alcohol, fruit solutions, toothpaste,
vinegar, ketchup, mayonnaise, gases, liquefied gases, etc.
Mass flow, density and temperature (the primary measured
variables) can be used to derive other variables such as
volume flow, solid contents, concentrations, and complex
density functions. i.e. One for all - multivariable
metering.
