LYSIMETER Russian patent published in 2017 - IPC G01N33/24 G05D9/00 

FIELD: physics.

SUBSTANCE: lysimeter includes a tank (1) with a soil block in communication with a vertically mounted tank (6), which is divided into a measuring tank (8) and a drainage well (9) by a vertical partition (10) and a tray (5). And the measuring tank (8) is made in the form of a float chamber, communicated by means of a pipe with a tank (1) of soil block, and in the partition (10) there is an opening with a water discharge device. A floating receiver (11) is connected to the upper end of a flexible hose (12), the other end of which is connected to the outlet (13) in the lower part of the partition (10) of the measuring tank (8). The floating receiver (11) is connected to a rod (14) freely mounted in the guides (15), which are rigidly connected by a lever (17) to the mechanism of changing the position of a floating actuator (16), which is in the form of a rod (18) with a screw pair (21) attached to the cover (20). The side wall of the tank (6) above the cover (20) is provided with a graduated rack (22) in the form of a scale opposite the pointer (19).

EFFECT: increase in the accuracy of the lysimeter and expansion of the application scope of the lysimeter.
