Analysis of Instrumental Characteristics of Agricultural Environmental Monitoring Station The agricultural environmental monitoring station is a special instrument for monitoring the agricultural environment, including simultaneously monitoring parameters such as wind direction, wind speed, sunshine, carbon dioxide, humidity, pressure, rainfall, soil moisture, and soil temperature in the environment. The instrument. The instrument can be used in field field microclimate automatic observers, has extensive applications in the fields of meteorological station construction, agroforestry climate monitoring, ecological environment monitoring, greenhouse control, highway railway operation and geological disaster monitoring, and has achieved very good results. All aspects of affirmation. Agricultural environment monitoring stations have three transmission methods: short-range limited transmission, medium-range wireless data transmission, and long-distance wireless data transmission. Among them, long-distance wireless data transmission mainly adopts modern and most advanced technologies GPRS, GSM, and 3G technologies, and realizes wireless rapid data transmission. At this point, the NL-5H compact automatic weather station can also be realized. In actual work, we can choose different transmission methods according to actual needs. In addition, the agricultural environmental monitoring station has a lot of storage space, there is no need to worry about the size of the storage capacity, the test data source is continuously sent to the computer, so the data can be monitored for a long time. Agricultural environmental monitoring stations use solar power, or city electricity, and can choose according to customer needs. Finally, the large-scale touch screen of the agricultural environmental monitoring station hosts real-time display of acquired data and graphs. The host can set the acquisition record interval, the host can record the acquisition data, and can also use the U disk to read the data. The instrument host and the bracket are easy to disassemble and disassemble, and it is easy to move.
Normally expansion tank is made by semi-transparent materials, such as plastic. The reason why use this kind material is that we can easily observed the liquid level directly through the box instead of opening the cap.
The operating principle of expansion tank is that, when people run cars, the temperature of the coolant circulating through the water jackets naturally increases which will increase pressure in the cooling system. When the pressure builds to a high enough point, the radiator cap allows that pressure to escape into the coolant reservoir through a small hose, called an overflow hose connected by the neck of the radiator to the expansion tank. Most of the coolant that is forced into the expansion tank returns to the radiator naturally after a few hours or when the engine is cold.
Without expansion tank, cooling systems would explode under pressure or the coolant would be forced from the overflow tube on the radiator and leak onto the road. It is advisable to check expansion tank regularly.
We can provide all kinds of expansion tank and brake fluid tanks with high quality and reasonable price. As we all know, expansion tank is a vital component in our car`s cooling system.

As engine coolant heats up, it expands. The coolant expansion tank provides additional storage for the expanding coolant and is commonly the location where coolant is added to the engine.
