<\/p>\nThe first volume measuring system with a 99,5% accuracy. Many companies are looking 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 VMS3000 of Jansen&Heuning makes clever use of high quality electronics and vision techniques.<\/p>\n
A laser beam is projected at an angle on the product profile on the belt and a special camera reads this projection 50 times per second. The resolution is better than 500 x 500 pixels. In other words: 12,5 Mb of information is processed each second. For this purpose the latest electronics is used.<\/p>\n
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 USB-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.<\/p>\n
<\/p>\n
Taking a large number of measurements on an equally large number of positions allows the system to achieve an overall accuracy of better than \u00b1 0,5%. The following example illustrates this:<\/p>\n

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.<\/p>\n\n\t\t |
