Abstract
A method and apparatus for measuring a quantity of particles deposited on a metal body to be coated with powder or the quantity of powder deposited per unit of time, especially on a moving body. The body is located in a space subjected to an electrostatic field and a quantity of powder deposited, possibly per unit of time, is measured by measuring a charge or current in a circuit connecting the field electrodes. An actual value deposited, indicated by a measurement, is used as a control parameter in a control circuit for adjusting an actual amount deposited to a set deposition amount which is adjustable.
