At present, wheat in most parts of Huaibei, Anhui Province has entered the wintering period and basically stopped growing. In other areas, wheat is still growing slowly, and rapeseed in the south of the Huaihe River is in a slow growth stage. In the middle of this month, most of Anhui Province was dominated by sunny to cloudy weather. There was no obvious effective precipitation along the Huaihuai area, and the drought continued. At the same time, it accompanied the cold wave weather process, which affected the growth of wheat vegetables to varying degrees. In a rainy and snowy weather process, the soil moisture in most areas is suitable, which is conducive to the growth and development of roots in the crops. Linyi Fertilizer Network Copyright
According to the weather forecast of the Anhui Provincial Meteorological Observatory and the current agricultural situation, the following countermeasures are proposed: Linyi Fertilizer Network Co., Ltd.
1. It is predicted that there will be obvious process of windy cooling and snowfall in the second half of this month. At present, wheat in the northern part of Huaibei is in a period of cessation, and other areas are still growing slowly. The wheat area should increase the intensity of field management, combined with the local wheat seedling growth conditions, appropriate measures to ensure warmth and antifreeze to ensure that wheat tillers are not frozen.

2. The rapeseed in most areas south of the Huaihe River is in a slow growing period, and some are in the bud stage. It is expected that cold air will go south in the next ten days and the temperature will be low. All localities should continue to strengthen the management of fertilizer and water in rapeseed land, improve the soil environment, promote root growth and development, and improve the cold resistance of rapeseed.

3. Strengthen the management of greenhouse vegetables and over-winter vegetables in the field, pay close attention to weather trends, prevent the dangers of rain, snow and cold weather, and strengthen the storage management of various winter vegetables and fruits. Linyi Fertilizer Network Copyright
4, all localities should strengthen the management of the orchard, check the orchard, if the fruit trees are found to snow in time to prevent snow from breaking the branches. Linyi Fertilizer Network Copyright

Microbend Mass Flow Meter
Sealand is a trustworthy manufacturer of Microbend Mass Flow Meter, Microbend Mass Flowmeter, Microbend Coriolis Mass Flow Meter, Microbend Coriolis Mass Flowmeter.
Site Selection for Mass Flow Meter Installation
a) Sensor stays away from mechanical vibration source, for example, pump. Use flexible pipe to connect meter with pipeline if inevitable. The housing of meter must be standalone, out of touch with any other device. There must be 3 times the size of sensor between 2 sensors if there are many flow meters on the same pipeline, to avoid resonance.
b) Do not install sensor on pipeline that easily expands with hot and contracts with cold, especially near expansion joint, which leads to a worse stability.
c) Sensor stays away from industrial electromagnetic field, such as large generator and transformer, better 5m at least. Such device influences the performance of drive coil and pickoffs. Make sure magnetic field intensity less than 400A/m.
d) Sensor shall be installed on lower pipeline, to be easily full of fluid.
e) Make sure Ex-mark meet application requirements if in hazardous area.
f) Build a sunshade if the meter is under direct solar radiation. g) Keep the meter from corrosive liquid.
