Abstract (en)
[origin: EP0297309A2] With this device, it is possible to measure and regulate directly the quantities of powder which are fed per unit time to a spray coating device for spray coating objects. For this purpose, the powder component in a powder/gas stream of the pneumatically conveyed powder is measured by a radiometric device (44) and the measured value is linked electronically, via an electronic evaluation device (42), with a value for the gas quantity which corresponds to the quantity of gas contained in the powder/gas stream and from this forms an absolute actual value of the quantity of powder conveyed per unit time. <IMAGE>
