Industrial dosing technology refers to the methods and technologies used to precisely dose materials in various production processes. Dosing can be either gravimetric (weight-based) or volumetric (volume-based), depending on the specific requirements and the type of material being dosed.
Microdosing technology
Microdosing is a specialized technique used to dispense very small amounts of material. It is particularly important in the chemical and pharmaceutical industries, where precise quantities of active ingredients or additives are required. Microdosing techniques enable high precision by dispensing material in tiny, precisely measured portions. This is especially important to ensure the consistency and quality of the end product. This is particularly important in sensitive production environments that place high demands on dosing accuracy and repeatability.
Technical details:
- Dosing of liquids: Accuracy of +/- 0.1 gram, with a scale resolution of 0.001 gram.
- Dosing of powders: Accuracy of +/- 0.5 gram, depending on the properties.
- Dosing speed: a few milliliters per hour are possible.
Weighing technology (gravimetric dosing)
Weighing technology is one of the most accurate methods in dosing technology and is based on precise weight measurement of the material to be dosed. Highly accurate load cells are used that detect even the smallest change in weight and adjust the dosage accordingly. This method guarantees precise dosing that not only takes into account the amount of material, but also fluctuations in material density.
Gravimetric dosing systems are particularly in demand where the highest precision is required. For example, in pharmaceutical production or in the production of high-purity chemical products.
Technical details:
The standard dosing accuracy is less than 1% of the amount to be dosed.
Depending on the requirements, dosing accuracies in the range of a few thousandths of a percent can be achieved. On request, we also offer a verifiable version that is suitable for precise measurements and legally regulated applications.
Volume flow measurement (volumetric dosing)
In contrast to weighing technology, volumetric dosing measures the volume of the material to be dosed. This technique uses all the volumetric flowmeters available on the market, such as Coriolis mass, magnetic-inductive, ultrasonic, and also mechanical meters, such as gear or turbine meters. This way, the material is transported and dosed in a defined volume. Volumetric flow metering is particularly suited to applications where a high dosing speed is required and larger tolerances in dosing accuracy are acceptable. This method is efficient and easy to implement, but can be affected by changes in material density or structure, making it more suitable for less precise applications.
Technical details: Dosing accuracies vary depending on the requirements and application, but are typically between 1% and 5% of the amount to be dosed. However, higher accuracies can be achieved in continuous processes. The volumetric flows range from a few liters per hour to several tons per hour and are individually adapted to the specific needs of your process.
Dosing accuracy and repeatability
Accurate dosing is a crucial factor in many industrial processes. Modern dosing techniques not only ensure precise adherence to the dosing quantities, but also a high level of dosing repeatability. These properties are particularly important for guaranteeing consistent product quality and low fluctuationsin production. The dosing technology from IFA Technology uses advanced sensors and control mechanisms to ensure reliable dosing even in continuous operation.

Frequently asked questions
What is microdosing and when is it used?
Microdosing technology is a precise method of dosing very small quantities of materials with great accuracy. It is used primarily in industries where the dosing of active ingredients or additives requires the utmost precision.
How does the weighing technology work in dosing systems?
In weighing technology, the material to be dosed is weighed using highly accurate load cells. This method enables very precise dosing and automatically takes into account fluctuations in the density of the material.
How is the dosing accuracy ensured?
The use of advanced measurement technology, sensors and precise control mechanisms ensures dosing accuracy. Automatic corrections for fluctuations in material density or material flow rate also help to keep the dosage precise.
When is volumetric dosing useful?
We recommend volumetric dispensing when speed is of the essence, space is limited, and a certain tolerance in dispensing accuracy is acceptable. It is suitable for materials with a stable density and applications where speed is of the essence.
Which dosing techniques offer the greatest accuracy?
Gravimetric dosing offers the highest accuracy, especially when material density fluctuates or high precision is required. Microdosing techniques are also very accurate, especially when dosing very small quantities.
