According to the Central Meteorological Observatory, on the 18th to the 20th, there was an obvious rainfall and weather process in most of the southern part of China. Among them, there were heavy rains in the south and east of the south of the Yangtze River, eastern and western Guangxi, most of Guangdong, and Fujian. The precipitation of the process was 60. ~130 mm, some areas are accompanied by strong convective weather such as lightning, local wind or hail. Affected by cold air, from 18 to 19, the southern Xinjiang Basin, the central and western Inner Mongolia, and the western part of Gansu have sand or dusty weather, and there are dust storms in the local area; northern Xinjiang, most of Inner Mongolia, and northeastern China have 4 to 6 winds, Xinjiang Shankou The wind power in the area can reach 8-9. Affected by cold air, on the 18th to 20th, there were scattered showers in parts of eastern Inner Mongolia, Northeast China, North China, Huanghuai and other places.
Specific forecast for the next 24 hours
From 1400 to 20:00 today, there are small to moderate rains or showers in eastern Tibet, western Sichuan Plateau, north-central North China, southern Jianghuai, southern Jiangnan, southern China, southern Sichuan Basin, and Guizhou. Among them, eastern Guangxi, central and western Guangdong, Heavy rain occurred in parts of southern Hunan, southwestern Jiangxi, and northeastern parts of the country, with heavy rains in parts of northwestern and southwestern Guangdong.
From 14:00 to 14:00 tomorrow, there are small to moderate rains or showers in eastern Tibet, western Sichuan Plateau, north-central North China, southern Jianghuai, southern Jiangnan, southern China, southern Sichuan Basin and Guizhou. Among them, eastern Guangxi and central and western Guangdong Heavy rain occurred in parts of southern Hunan, southwestern and northeastern Jiangxi, northwestern Fujian and other places, and heavy rains (50-70 mm) were found in parts of northwestern and southwestern parts of Guangdong and northwestern Fujian. Most of South China has short-term heavy precipitation, and there are strong convective weather such as hail, thunderstorm and strong wind in some areas. There are 4 to 6 winds in northern Xinjiang, western Gansu, Inner Mongolia, northeastern China, and eastern North China, and the wind power in Xinjiang's Shankou area can reach 8 levels. Some areas of Xinjiang's Nanjiang Basin, western Gansu, and Inner Mongolia's central and western regions have sand or dusty weather, and local dust storms.
Agricultural advice:
1. In the southern region, please continue to defend against strong local precipitation and its urban and rural accumulations, mudslides, landslides and other disasters, and to defend against strong convective weather such as lightning, hail and short-term winds, to avoid sheds and temporary turbulence caused by strong convective weather. Casualties caused by structures, outdoor billboards, and collapse of trees.
2. Eliminate the accumulation of water in the field in time, clear the ditch;
3. Rainy road slippery, poor visibility, please pay attention to traffic safety.

The meter consists of mass flow sensor and transmitter. Mass flow sensor is a phase-sensitive resonant sensor based on Coriolis effect, composed of vibration tube, signal detector, concussion driver, structural support, shell, etc.
Mass flow transmitter is a micro-programming-centered electronic system, which supplies
thrust to sensor, transforms sensor signal into mass flow signal & others, and improves
accuracy in accordance with temperature parameter.
It`s composed of switching power supplier, guard grating, core processor board, display
module, etc., installed in a ex-proof junction box. Switching power supply offers power for
transmitter; safe grating isolates sensor and transmitter intrinsically; core processor detects
& processes sensor phase signal, sends mass flow signal and process communication.
