Abstract
A process for automatic filling with products, particularly of gas into gas cylinders, utilizes electronic comparison of the data stored in a data carrier located on the tank with the actually measured weight of the tank makes it possible to determine the degree of residual filling in the tank as well as to ascertain whether the tank weight is too low which, under certain circumstances, can give rise to safety risks and, in response, to either remove the tank from the filling process or else to fill it. The process and the device function fully automatically, so that it is possible to save personnel costs.
Claims17
In a process for automatically filling a tank with products, in which a parameter selected from the group consisting of the weight and the internal pressure is measured in order to ascertain the degree of residual filling in the tank, and the tank is filled until a desired degree of filling--determined by measuring the parameter--is reached, the improvement being in that the tare data on the tank parameter selected from the group consisting of the tank weight and the maximum permissible internal pressure of the tank that is needed to ascertain the degree of filing of the tank is read from a programmable data storage element that is affixed to the tank, the values read are compared with the measured values and, on the basis of the calculated difference which is then compared to a limiting parameter selected from the group consisting of a maximum permissible difference and a minimum and a maximum value likewise stored in the programmable data storage element, the filling is carried out within the maximum permissible differential value until the permissible filling parameter selected from the group consisting of the filling weight and the permissible filling pressure has been reached, which is likewise read from the programmable data carrier.
In a device having scales, a tank and a filling mechanism, the improvement being in that the tank is linked to an automatically readable data carrier in the form of a programmable data storage element affixed to the tank and the scales are linked to a transmitter that transmits weight data to a computer which is associated with the filling mechanism and which compares the data stored on the data carrier with the measured data transmitted by the scales to the computer.
