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.

I have installed a RTD whose length is 2250mm(RTD stem length), but it's upper 200 -250mm is out of the reactor, and this upper 200mm stem is surrounded by atmospheric temp. And the lower portion i.e. 2000mm is in contact with the measuring fluid, then does the final measuring temp. Gonna change as the upper 200mm RTD stem is out of reactor?
