Description

Известные устройства дл измерени и регистрации испарени с поверхности водоемов в естественных услови х не обеспечивают производства отсчетов и регистрации величин испарени с заданной степенью точности.The known devices for measuring and recording evaporation from the surface of water bodies under natural conditions do not provide for the production of readings and the recording of evaporation values with a given degree of accuracy.

Описываемое устройство свободно от указанного недостатка. На чертеже дан вертикальный разрез устройства .The described device is free from the indicated disadvantage. The drawing shows a vertical section of the device.

Открытый сверху и заполненный водой бак 1 устанавливаетс в водоеме на поплавках 2 с таким запасом пловучести, чтобы при испарении воды с поверхности бака 1 исключалась возможность его вертикальных перемещений относительно уровн воды в водоеме.The tank 1, which is open at the top and filled with water, is installed on the floats 2 with a buoyancy reserve so that when the water evaporates from the surface of the tank 1, the possibility of its vertical movements relative to the water level in the pond is excluded.

Определение величины испарени с поверхности бака / производитс по перемещению установленного в нем с некоторым запасом пловучести сосуда 3, внутренн полость которого частично заполн етс водой и дл автоматического уравновещивани соединена сифонной трубкой 4 с водоемом .Determining the amount of evaporation from the surface of the tank / is made by moving the vessel 3 installed therein with a certain reserve of buoyancy, the internal cavity of which is partially filled with water and for automatic balancing is connected by a siphon tube 4 to the reservoir.

При испарении воды с поверхности бака / сосуд 3 погружаетс в воду , поддержива посто нный уровень воды в баке 1, относительно которого определ етс глубина погружени 3. При этом уровень воды в баке / все врем остаетс выше уровн воды в сосуде 3 на некоторую , первоначально установленную , посто нную величину.When water evaporates from the surface of the tank / vessel 3 is immersed in water, maintaining a constant level of water in tank 1, relative to which the depth of dip 3 is determined. At the same time, the water level in the tank / all the time remains above the water level in vessel 3 by some fixed, constant value.

Дл обеспечени производства отсчетов сло испарившейс воды с поверхности бака / с нужной степенью точности отношение площадей поперечного сечени бака / и сосуда 3 выполн ют равным заданному масштабу измерений.In order to ensure the production of samples of the layer of evaporated water from the tank surface / with the required degree of accuracy, the ratio of the cross-sectional areas of the tank / and the vessel 3 is equal to a predetermined measurement scale.
