METHOD AND DEVICE FOR MEASURING THE VOLUME OF OBJECTS MADE OF HYGROSCOPIC MATERIALS WITH A COMPLEX GEOMETRY, BY MEANS OF A PNEUMATIC SYSTEM.

摘要

A method and a device for measuring the volume of objects made of hygroscopic materials with a complex geometry, by means of a pneumatic system. The device comprises a system of two chambers with built-in absolute pressure transducers, one chamber receiving the object to be measured and the other being the chamber where compressed air accumulates. The compressed air supplied to the system first passes through a cleaning system. The pressure of the air incorporated is controlled by means of a pressure limiter. The volume of the object is measured on the basis of the volume of the two chambers and the reading of the pressures reached in said chambers during the measuring cycle, as one of the chambers is pressurized and then the valve that places them in communication is opened. The method may be used for hygroscopic materials of complex geometry, such as wood, pellets, granular feed or soil.
