E601B surface evaporator

E601B type water surface evaporator is an instrument for observing evaporation of water surface on evaporation station, and can be used by hydrology and meteorology departments.
The product has anti corrosion, anti cracking, good insulation, prevent the advantages of small water and ground intense heat exchange, high accuracy, convenient use, long service life, State Bureau of technical supervision has been identified as the only national standard instrument of evaporation observation and included in the national standard "GB11829-89" by the Ministry of water resources, Ministry of power, Chinese Meteorological Bureau of Chinese Academy of Sciences, as a product, in the country to promote the use of.

Working principle
The accurate liquid level in the evaporation tank and the liquid level difference within a given period of time are measured with the probe, which is the evaporation of water in this period. The whole measuring pin is mounted on the socket of the evaporating barrel. When the dial is rotated, the measuring needle moves up and down, so that the measuring needle touches the water surface. The height of liquid level is measured by vernier reading. When the tip touches the water surface, the audio circuit generates oscillation and sends out sound to the worker to touch the water signal of the needle tip.
The instrument consists of a sounder, socket probe, evaporation barrel, a pen, a rubber tube, overflow barrel.
