LYSIMETER Russian patent published in 2018 - IPC G01N33/24 G05D9/00 

FIELD: agriculture.

SUBSTANCE: lysimeter includes a tank (1) with a soil monolith, a drip tray (5) and water level controls, a water tank (28) that is installed above the pallet (5), the connection pipe is hydraulically connected to the soil monolith container (1). Also the lysimeter is equipped with the equalization chamber (22) with float (27) in the form of a biconvex lens in the bottom of the tank, which is divided into two unequal parts horizontal partition (15). Bottoms (14) of the first part (8) capacity (6) with additional output pipe (18) housing (6), the lower part of the pipe (18) which is secured by means of threaded connection (23) with a casing of the equalization chamber (22) with float (27), and the upper part of the outlet fitting (18) related to housing (16) and placed in it a float (19), cavity which communicate between themselves. The inlet pipe (17) and the housing (16) with the float (19) are connected to the water tank (29). Wherein, the case (16) and the float (19), hosted in it, made spherical, and locking elements (20 and 21) are made in the form of conical needles, with input (17) and (18) tubes have conical locking socket (24 and 25). The locking socket (25) of the outlet pipe (18) is connected to the recess (26) in the form of a ball segment of the compensation chamber (22), and the counter (31) is configured as a water flow measurement unit.

EFFECT: reducing the labor intensity of control and increasing the accuracy of regulation and measurement when using monoliths of soil of any size, expanding the field of application.
