FFZ-01 type digital surface evaporation sensor is used for instrument in different time variation of evaporation observation, it is made according to the standard of "People''s Republic of China water conservancy and electric power department of evaporation observation standard" SD265-88, supporting the use of evaporation directly with the diameter of 618mm or 20m2 with standard evaporation pool, used to measure water evaporation quantity monitoring instrument. Evaporation sensor measurement accuracy, it is much more stable than ultrasonic type and other types, and can real-time remote transmission, suitable for various types of equipment in various regions and evaporation stations.

2 characteristics
Digital sensor has no temperature drift and time drift, and its performance is stable for a long time;
High resolution and high precision;
It can also be observed normally under the condition of wind wave and rainfall, without losing accuracy;
Resistance to electromagnetic interference, even after the power outage, the output data is still correct;
And with the evaporation, water, automatic water supply device, collecting and recording device supporting the use of automatic monitoring to achieve the evaporation process.

3 function, scope of use
Combined with automatic water supply control device, a simple automatic telemetering evaporation station is made up;
The digital recording evaporator is constructed with the evaporation data recorder to realize the automatic record of evaporation process;
With the JFZ-01 digital gauge, digital flowmeter consists of automatic overflow, evaporation and rainfall stations, equipped with basic evaporation station network, evaporation and rainfall process automatic observation, recording and transmission.
