<p>1. Apparatus for the electronical, continuous measurement of the volatilization of an open water surface and of an amount of falling down precipitation by a measuring tank (1) filled with water, which tank is in flow connection with a water containing sensing bottle (12) of comparable minor surface, which bottle includes a sensor (2) for the liquid level having outputs, which can be controlled by a circuit (L) of a refilling unit (4, A, alpha, beta, 6) for vaporized water and a discharge unit (7, D, gamma, delta, 9) for deposited water, respectively, which units are separately connected to a counter circuit (G, H), at least one of which is connected to a recording apparatus (K), characterized in that the liquid level sensor (2) consists of a float (3) and a sensor spool, that the flow connection between the measuring tank (1) and the sensor bottle (12) is a tube of less diameter, that within the refilling unit (4, 5, 6) a refilling tube (5) of any diameter is connected through a first valve (4) to a water tank (10), that the refilling tube (5) is provided with two position sensors (alpha, beta) having an adjustable distance from one another, that the discharge opening of the refilling tube (5) is connected through a second valve (6) to the sensor bottle (12), that within the discharge unit (7, 8, 9) a tube extends from the sensor bottle (12) through a third valve (7) to a discharge tube (8) of any diameter, being provided with two position sensors (gamma, delta) having an adjustable distance from one another and that the discharge opening of the discharge tube (8) extends through a fourth valve (9) into the open air.</p> |
