Method and apparatus for measuring and regulating the flow rate of powder in a powder spraying device |
摘要 |
An apparatus and method for accurately determining the quantity of powder flowing in a spraying device includes a power density measuring element for measuring the powder density of the powder/gas mixture flowing in the spraying device and a device for measuring the flow rate of the pure gas prior to its mixing with the powder. Signals representative of the powder density and gas flow rate are generated and transmitted to an electronic evaluation device which calculates from these measurements the absolute flow rate of the powder per unit time.
