GENERAL
The advantages of Coriolis mass-flow measurement are self-evident. It comes as no surprise, therefore, to find that this principle is used in a huge range of industry sectors, including pharmaceuticals, chemicals and petrochemicals, oil and gas, food, and also in custody transfer applications in general.
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.
One for all - multivariable metering. The ability to measure several process variables all at the same time opens up completely new application fields. 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. |
