Automatic emptying method for material in container e.g. gas cylinder

摘要

The method is established by measuring the weight or the inner pressure of the residue inside the bottle. The tare data of the bottle weight and/or the maximum permitted inner pressure of the bottle (1), needed for establishing the filling level in the bottle, are obtained from a programmable data storage, provided at a transponder (9). The read-off values are compared with measured values and, based on a computed difference, which is compared with a maximum permitted difference and/or minimum and maximum value, stored also on the programmable data storage. The results while filling, with the keeping of the maximum permitted difference value, until the permitted filling weight or the permitted filling pressure is reached, can also be read off from the programmable data carrier.
