Patent number: 6494645Abstract: The method according to the invention is suitable for determining a powder quantity in a container and for determining a change in powder quantity, i.e. the powder quantity that is supplied from the container(s). The powder is fluidized in the container, the pressure of the fluidized powder in the container is measured to determine the pressure of the fluidized powder or the change of the pressure between two measurements, wherein the powder quantity in the container, or which was supplied from the container between two measurements is calculated from the pressure or the change in pressure. By the method according to the invention it is possible by a simple pressure measurement to determine the powder quantity which is supplied per time unit from the container and which is sprayed by the coating apparatus, and therefore to determine the supplied powder mass flow.Type: GrantFiled: October 2, 2000Date of Patent: December 17, 2002Assignee: Wagner International AGInventors: Kurt Seitz, Horst Adams

Patent number: 6029527Abstract: A device and method of measuring and controlling the flow rate of a fluid determine analog process variables which are dependent on a volumetric flow of the fluid, and the values thus obtained are converted into digital values, the latter being corrected by an offset value which is dependent on a change of the operating parameters of analog components of the measuring system occurring in the course of operation of the system. To obtain the offset value, an analog process variable is determined during interruptions in operation, when the volumetric flow is zero, and converted into a digital value. This digital value is memorized and used as the offset value when operations are resumed. The digital corrected measured values are supplied to a digital signal processor and the flow rate control is carried out digitally. Preferably, at least one parameter memory is provided for the digital control.Type: GrantFiled: March 19, 1998Date of Patent: February 29, 2000Assignee: Wagner International AGInventors: Kurt Seitz, Horst Adams, Markus Hasler
