Volume Measuring Systems

The first volume measuring system with a 99,0% accuracy.
Many companies have been waiting for years for a reliable system for measuring volume flow of bulk products like peat, compost, soil, rubble, sand etc. Not all the products are sold by weight. The VMS2000 of Jansen & Heuning makes clever use of high quality electronics and vision techniques.

How does the machine work so many companies have been waiting for?

A laser beam is projected at an angle on the product profile on the belt and the CCD-camera reads this projection 50 times per second. The resolution is better than 500 x 500 pixels with a frequency of 50 Hz. In other words: 12,5 Mb of information is processed each second. For this purpose a digital signal processor is used.

The area of the product cross section is calculated and in combination with the measured belt speed, the volume and the capacity can be determined. These data are processed in a PC with an RS485-port. We supply the required software. As an option we deliver an English software protocol, which allows the PLC to perform the control and read-out functions completely or partially by itself.

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:

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.

Options
Ask Jansen & Heuning for more information if you wish to use the VMS2000 in the following situations:

• Control per batch and delivery by volume
• Continuous measurement of bulk density
• Read out via a 4-20 mA analogue port
• Potential free contacts
• Data file display for your data processing
• Defining of correction factors according to DIN and CEN for the compost/peat industry
• For all other questions that haven't been addressed so far, contact Jansen & Heuning and we will help you find the answers
