Meteorological observations are an indispensable part of field work. It uses sight and small weather station instruments to observe and measure field weather. Field meteorological observation data plays a decisive role in farming operations. As observers must have solid observation technology knowledge and skilled operating skills, should try to avoid misunderstandings, in order to ensure access to the most representative, accurate, comparative observations of field weather, provide a strong guarantee for agricultural production.
The
air in the circulating system of the air conditioning system is dissolved in
varying degrees. The solubility of air varies with the temperature and pressure
of water. The higher the temperature, the smaller the solubility; the greater
the pressure, the higher the solubility. With the constant change of
temperature and pressure in the pipeline, the dissolved air in the water also
precipitates from time to time and then dissolves. When the air is released
from the water, it begins to converge into tiny bubbles, which gradually
accumulate into larger bubbles and forms air bags. Bubbles and air bags in the
pipeline are harmful to the system, such as it will affect the heat exchange
efficiency, it will form noise; cavitation on pipe fittings, increase the power
loss of the pipeline and so on.

MBS02/05/07 Micro Bubble Separator can effectively collect all kinds of tiny
bubbles in water, automatically guide them to the top of the valve body, and
discharge them from the system by automatic exhaust structure. Because it`s
working principle is to absorb micro-bubbles by internal structure, the smaller
the flow velocity in the valve body, the better the removal effect of
micro-bubbles.

1. Must have a solid observation of technical knowledge and skilled operating skills 1. 1 understand the basic requirements of the observation work is to do a good job of the observation of the work is highly concentrated, highly dispersed is the characteristics of meteorological observation work, the observer in the observation work on agriculture and forestry Microclimate acquisition systems, environmental conditions, methods of operation, observation time, and the accuracy of factors must be strictly enforced by uniform regulations and post accountability. To be realistic and serious, it is forbidden to forge records, prohibit early, late, missing, and missed measures, and try to make the meteorological observation data close to its natural state, so as to have objectivity and credibility, otherwise it would not make much sense.
1.2 Meteorological observation is a very comprehensive natural science observer. In addition to mastering the technical knowledge of the professional, it should also understand the relevant subject knowledge beyond it, so that it can be organically linked and used. Meteorological observation is a methodical work. Many aspects focus more on mastering skills. Observers should combine theory with practice to master operational skills and standardize them.
2. Observations and records: First of all, we must make preparations for observation. Second, the instruments, equipment, and tools for the field microclimate automatic observation instrument to be used for observation must be prepared in advance.
3. Acquire accuracy of each observed data observation data is to reflect the true degree of meteorological elements. It depends on the accuracy of the instrument and the method of observation. Observers must treat each observation record carefully, carefully, and cautiously in the observation work to ensure the accuracy of the observation data.
4. Observers should constantly learn new knowledge, master new techniques and new methods, and keep up with the times.
