摘要：
The level detector device comprises a variable pressure chamber and a plurality of fluid ejection bores downstream of the chamber, through which a fluid under varying pressure is ejected into a container containing a particulate or powdery material, and detects changes of pressure in the chamber which is representative of a rate of closure of the fluid ejection bores dependent on the level of the material in the container.
