A system is provided for determining an accumulation per unit time and for determining a layer thickness of accumulation of bulk goods such as pulverulent, granular or flaky goods. Preferably, the system uses diffused reflected light from the bulk goods being deposited on a moving surface to determine the rate of accumulation and an optical system including a further light beam and photocell to measure the layer thickness of the accumulation. An integrating means may be provided for ascertaining a cumulative total accumulation within a predetermined period of time.
