An apparatus for detecting the level or quantity of a particulate material contained in a vessel by means of an agitating and/or delivering member while agitating the particulate material which needs to be agitated from time to time. The agitating member is arranged in the vessel for rotation about a horizontal axis, the center of gravity of the agitating member deviating from said horizontal axis. A driving and a driven disks disposed in spaced juxtaposed relationship constitute drive means for driving the agitating member. Arranged between the driving and driven disks is coupling means which, while permitting the disks to rotate relative to each other through a predetermined angle, connects the two disks to each other when the disks reach an end of said angle. Thus, when the agitating member is drawing, during its movement, near the upper surface of the particulate material in the vessel, it is disconnected from the drive source due to its eccentricity while the two disks are moving through said angle, and further moves by its own weight till it reaches the upper surface of the particulate material where it temporarily remains stationary. The angular position reached by the driven disk at this time indicates the level or the gravity of the particulate material in the vessel. Detection of the level of particulate material can be readily achieved by observing the angular relationship of the two disks at the time when the agitating member becomes stationary.

An apparatus for detecting the level of a particulate material contained in a vessel comprising: a. a driven member rotatable about a horizontal axis in said vessel, a material engaging member affixed to said shaft and having a portion extending radially from the axis of rotation of said shaft and being rotatable with said driven member, said material engaging member having its center of gravity at a position based on the axis of rotation of said driven member; b. a driving rotary member disposed in spaced aligned relationship to said driven member and being rotatable in a driving condition and being non-rotatable in a detection condition during which time said material engaging member falls by the influence of gravity onto the surface of the material; c. a lost motion drive connection between said driven rotary member and said driving rotary member, permitting relative rotation therebetween through a predetermined angle and the driving of said driven member by said driving member; and d. means for detecting the angular position of said driven rotary member when said driving member is in a detection condition, at which time said material engagement member rests on the upper surface of the particulate material in the vessel, and in arriving in this position, rotates said driven member through an angle relative to said driving member, in accordance with the level of the material and the movement of said material engagement member under the influence of gravity to the surface of the material.
