What is the density in dosing technology?

Density refers to the mass of a material per unit volume. It is an important physical property that indicates how much mass of a substance is contained in a given volume of space. Density is often measured in kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³). Density plays a crucial role in dispensing technology, as it must be taken into account when precisely dispensing liquids or pastes. Density is used to calculate the volume of the material to be dispensed in relation to its mass, thus ensuring accurate dispensing quantities.

This picture shows how the density of water affects the behaviour of objects in water. The scale weight sinks to the bottom of the glass because it has a greater density than water. The cork, on the other hand, floats because it has a lower density than water.

What functions does density assume within metering technology?

Density plays a crucial role in dispensing technology, as it is often referred to in order to determine how much filler is contained within the material. Its function within dispensing technology can be described as follows:

Calculation of volume:
To achieve accurate dispensing of a material, the volume of the material to be dispensed must be known. Density is used to calculate the volume of a material in relation to its mass.
The formula is: Volume (V) = Mass (M) / Density (ρ).

Adjusting the dispensing volume:
Once the density is known, the metering pump can be adjusted to deliver the desired amount of material per unit time. This is especially important in applications where precise metering is required to ensure high product quality and process control.

Waste prevention:
Material can be saved by taking density into account. The metering system ensures that only the required amount of a material is used, which can lower costs and reduce environmental impact.

Control of processes:
In many industrial processes, accurate metering is critical. Density makes it possible to adjust the dosing amount according to process requirements, ensuring product quality.

Error prevention:
Density helps prevent errors during batching. By knowing the exact density of a material, variations or deviations in feeding can be detected and corrected.

Optimizing dispensing systems:
Knowledge of density allows engineers and technicians to optimize dispensing systems to meet the specific requirements of an application.

In dispensing technology, accurate consideration of density is critical, especially in industries such as food processing, chemical, pharmaceutical, environmental, and many others where precise dispensing and accurate control of materials are required. Density is an essential variable in ensuring that the right amount of material is dispensed at the right time and in the right place.
