Coriolis: Flow control of smallest liquid quantities

How you can use the Coriolis principle to dose even the smallest amounts of liquid – precisely, quickly and with reproducibility

Typical challenges involved in dosing very small amounts of liquid

The challenge of dosing very small amounts of liquid relates to dosing precision: One drop too much or too little makes a big difference to ingredients, additives or aromas. It can negatively influence the quality of entire production batches. Our mass flow meters and controllers prevent unwanted dripping or an excessively sluggish response in the upstream dosing system.

Independent of pressure and viscosity
Constant flow rates – even at different speeds
Low pulsation
Precision and accuracy for maximum output and consistent quality

The solution: MFM/MFCs for the smallest amounts of liquid

The mass flow meters (MFM) and controllers (MFC) Type 8756 from Bürkert operate according to the Coriolis measuring principle:

Independent of medium, temperature and pressure or viscosity
Quick, precise and reproducible
Digital or analogue integration thanks to existing interfaces
Seamless tracking of process sequences
Continuous documentation for customers
Configuration memory included – simple device changeover possible

Mass flow meter
MFM Type 8756
The mass flow meter measures liquid flow rates up to 25 kg/h. It is designed to cope with minute quantities and aggressive liquids. Its accuracy of 0.2% of the measured value makes it one of the most accurate flowmeters for small liquid flow rates

Mass flow controller
MFC Type 8756 with micro annular gear pump
A mass flow controller with a micro annular gear pump not only measures the flow rate but can also control it with a high degree of precision. A very high resolution and smooth pump operation guarantee the exact setting of a desired set-point flow rate. Due to the high-quality wetted materials, the pump can also be used with liquids.

How Bürkert mass flow meters/controllers benefit you

Completely free of splashes, drops, foam or bubbles – consistent high quality during the dosing process

The Coriolis principle enables constant and interference-free measurement and optional control of flow rate values over extended periods

The flow-measuring principle operates independently of medium, temperature and pressure or viscosity

The mass flow meters and controllers react flexibly to changes in the dosing modes within a production process

Reproducible production processes mean shorter settling times

Mass flow meters and controllers can easily be flushed

The perfect solution for many industries

Although they appear to operate very differently at first glance, different industries face the same challenges when it comes to additives: This is where effect, taste, smell, consistency or appearance play an important role. Therefore, dosing must be carried out precisely to guarantee the consistent quality of the end product. In addition, it must occur quickly to achieve higher process utilization.

Pharmaceutical: Ultra-precise dosage of additives determines the composition and effectiveness of drugs and medicines.
Chemicals: High-precision dosing of individual substances is essential in the case of chemicals.
Food & beverages: An exact measurement ensures the reproducibility of appearance, consistency or taste.
Cosmetics: For additives such as the fragrances used in care products, exact dosing is essential.

The Coriolis principle

The MFM/MFC Typ 8756 devices enable quick, reliable and precise dosing for consistent quality of the end products. The Coriolis principle makes it possible: The liquid is measured independent of the medium, temperature and pressure.

Unrivalled precision and speed
Reliable and flexible
Once adjusted, it can be used for every liquid

Arguments in favor of MFM/MFC Type 8756

In addition to saving raw materials and additives, thus also saving money, you are safeguarding your product quality.

The Coriolis principle guarantees exact measured values (+/- 0.2% of meas. val. +/- 0.0014 kg/h); the zero point stability of the flow sensor also contributes to the measuring accuracy.

Rugged construction, built to last – ensuring that vibrations cannot impair your product quality.

Do you want to dose different media? With mass flow meters and controllers from Bürkert, you only need one device type to do so in the future.

Reliable and flexible – thanks to the high measuring span of the devices and their constant accuracy, you need fewer measuring and control devices overall.

Looking to work with greater speed and precision yet ensure consistently high production quality? Discover how you can also cut costs while doing so.

Assumptions: The measurement based on the Coriolis principle is compared with the gravimetric method, since the two methods are equivalent in terms of precision. The same peripherals (valves, pumps) as well as differences in accuracy are assumed. In addition, the same costs are applied for dosing. The plant runs 24/7.
