The advantages of measuring Coriolis mass flow rates are obvious, because this measurement principle is not affected by physical factors such as driving can be measured all types of fluids, detergents and solvents, oils and fuels burn, vegetable oils , animal fats, latex, silicone oils, toluene, benzene, alcohol, methane, fruit juices, toothpaste, cooking oils, vinegar, ketchup, mayonnaise, gases, licuifizados gases (butane, propane, natural gas), etc. .
Coriolis flowmeters simultaneously recorded the fluid density and mass flow, and with the help of temperature sensors can also monitor the temperature of the fluid. Certainly, then, we designate this type of measurement as "multi-variable measurement."
The primary measurement variables, ie mass flow, density and temperature, calculate and display other variables derived from them, such as volume flow, solids content or concentration values or densities des derivatives (for example, standard density, ° Brix, ° Baurné, ° API, ° Balling, ° Plato). Modern measuring systems and are equipped with transmitters that calculated and directly provide high measuring these variables. The remarkable characteristics of these teams Coriolis new horizons have opened
- Mixing and packaging of various commodities
- Process control.
- The measurement of fluids with rapidly changing densities
- The control and supervision of product quality
These are some of the reasons why the Coriolis principle has been established as a measurement technique tested in the last ten years. Coriolis flowmeters are often used in chemical processes, mainly in response to the following:
- They are a direct method of measuring mass flow measurement with high accuracy (typically 0.1%)
- The variety of possible materials for the measuring tubes gives them versatility.
- Your child container gives them greater security.
Many applications in the food industry have flowmeters of this type, for example for filling dosiflcación or small amounts of ingredients (Fig. below). Coriolis flowmeters are also becoming widely available in gas counting applications at low and high pressure, such as compressed natural gas (CNG). In the market for flowmeters are also suitable for many applications in Custody Transfer.

The advantages described for this type of flowmeters based on the Coriolis principle and have opened some time since new applications for these devices. It shows, moreover, that the market for such equipment will continue to grow at current rates or even to expand in the coming years.
The characteristics of Coriolis flowmeters are particularly attractive and promising for applications in the past were covered with I-measurement techniques "traditional". The acquisition cost of ownership is one of many factors that come into play in this regard. It includes not only the initial cost of acquisition, but also covered the expenses and investments during the entire life cycle of the equipment. Surprisingly, Coriolis flowmeters show life-cycle costs very low, because their maintenance is relatively low and show a high level of flexibility in a variety of process conditions. Other advantages that deserve mention are:
- No moving parts inside the measuring tube
- No need filters
- No need to separately measure the density
