Description Volume measuring system (VMS3000)
The Volume Measuring System VMS3000 from Jansen&Heuning is a proven solution for accurately measuring the volume of bulk materials on conveyor belts. The system combines advanced vision technology with high quality electronics. This integration ensures stable and consistent measurements, even under varying process conditions. With this technological approach, the VMS3000 is among the first systems achieving a reliability of more than 99 percent in volume measurement of bulk materials.
How does the volume measuring system work
A laser beam is projected at a fixed angle onto the product profile on the conveyor belt. A camera registers this profile and reads the image more than fifty times per second. The resolution is approximately 1000 by 1000 measuring points. As a result, around 50 MB of data is processed per second. This requires and utilises the latest electronics.
Based on this data, the cross sectional area of the product is determined. In combination with the measured belt speed, the volume flow and capacity are calculated. The measurement data is read via a USB connection on a PC. The required software is supplied as standard. Optionally, an English software protocol is available, allowing the control and read out functions to be fully or partially integrated into a PLC system.
The results
Taking a large number of measurements on an equally large number of positions allows the system to achieve an overall accuracy of better than ± 0,5%. The following example illustrates this:
| Input data | Height measuring on every |
| Belt speed 1 m/s | 2 cm belt length |
| Belt width 1000 mm | 2 mm belt width |
Up to now various volume measurement systems have been delivered and are functioning to the complete satisfaction of our customers. We have gained valuable experience in the field of compost, peat, salt, sand, gravel and cover soil.
Application Volume Measuring System VMS3000
Volume measuring systems are applied in processes where the flow rate and quantity of bulk streams must be continuously and reliably determined for bulk materials transported on conveyor belts.
Industrial bulk processing
In sectors such as mining, building materials and recycling, volume measuring systems are used for materials such as sand, gravel, ores and rubble. They support process monitoring and ensure a constant feed to installations.
Agriculture and horticulture
In the agricultural sector, volume measuring systems are used for products such as grain, peat, potting soil and compost. They support dosing, mixing processes and quality control.
Process industry
Within the chemical and food industries, volume measurements are used for raw materials and semi finished products. This is essential for recipe control and traceability.
Logistics and storage
During handling and storage of bulk materials, for example in ports and terminals, volume measuring systems are used to register and control incoming and outgoing flows.
Process optimisation and billing
In addition to physical applications, volume measuring systems support process optimisation and administration. They provide reliable data for capacity calculations, energy consumption and in some cases billing based on processed volumes.
In summary, volume measuring systems are used wherever bulk flows must be accurately measured for process control, monitoring and registration.
