Rika solar radiation sensor factory for shortwave radiation measurement

Agriculture plays a large role in our society, employing about one third of the world’s available work-force, globally. Cultivated land use has increased four-fold over the past two centuries but has remained fairly constant in the US for the past few decades. Efficient use of this land is essential to achieving key goals of healthy plants and increased productivity and profitability. This can be achieved with the help of more efficient agricultural practices to increase output while minimizing input costs that can range from materials to electricity to labor along with the valuable natural resource of water. Measurement can greatly aid in this overall goal to improve plant health and yields, to preserve valuable resources, to use inputs more effectively, and to minimize the overall impact on the environment. Site-specific measurements in your microclimates offer both immediate and relevant data for your particular operation and are useful aids to help predict, manage, and prompt corrective action, as needed. Readings can be made on an occasional or ongoing basis with either a portable device or a continuous monitor, typically fitted with logging or alert capabilities. Weather monitoring, for example, offers a variety of measurement options that can be tailored for your specific operation including light (see more about Light Measurement) for optimized photosynthesis and overall plant growth and health, leaf wetness and relative humidity which can affect disease pressures, soil moisture to ensure moisture penetration and to schedule irrigation events, along with temperature, wind speed/direction, rainfall and more. Evapotranspiration (see more about evaporation sensor)  can be calculated to help schedule irrigation events and to assist with IPM (integrated pest management) decisions. Insect and disease models can forecast risk and assist with pesticide treatment schedules and provide documentation for these decisions. Other common measurements include nutrient levels to evaluate plant, soil, and input levels, detect plant stress early, and time fertilizer applications. pH measurements help confirm the availability of  nutrients in your soil as well as the effectiveness of fertilizer solutions, electrical conductivity (see more about monitoring salinity) to evaluate soils, irrigation water and fertilizer solutions to avoid nutrient deficiencies, and compaction to determine soil strength. Operation-specific and microclimate measurements can be very convenient, affordable and, most importantly, can ultimately help you to make informed decisions, optimize field management, and utilize more efficient practices in so many facets of your operations including fertilizer and herbicide/pesticide applications, irrigation schedules, timely reaction to frost risk, harvesting, storage and transportation, and the overall growth and management of healthy crops.

An anemometer is an instrument for measuring the velocity of air. There are many kinds of anemometer. The commonly used one in meteorological stations is the wind cup anemometer, which consists of three empty parabolic cone cups fixed on the bracket at 120° each other to form the induction part, and the concave surface of the empty cups is in the same direction. The whole induction part is installed on a vertical axis of rotation. Under the action of wind force, the wind cup rotates around the axis with a speed proportional to the wind speed. Then, how to use an anemometer to measure the wind volume and wind speed? Please see the below instruction for reference. 1. Check whether the fan is in normal operation before testing, and must measure the size of the tuyere and air duct to be measured on the spot. 2. For unidirectional flow (laminar flow) clean room, the air volume is determined by the product of the average wind speed of the room section and the clean product. (Take the section of the filter 0.3m perpendicular to the airflow as the sampling section, set no less than 5 test points on the section according to the distance between test points should not be greater than 0.6m, and take the arithmetic mean of all readings as the average wind speed.)The vertical unidirectional flow (laminar flow) clean room is determined by the horizontal section of 0.8m ~ 1m on the ground. The horizontal unidirectional flow (laminar flow) clean room is determined by the vertical cross section of the air supply surface of 0.5m ~ 1m; The number of test points on the section should not be less than 10, the spacing should not be greater than 2m, evenly arranged; 3. For the tuyere with filters, the air volume is determined by the product of the average wind speed of the tuyere section and the net cross-sectional area of the tuyere. (The average wind speed is obtained by not less than 6 evenly arranged test points on the tuyere section or the section referring to the auxiliary air duct.) 4. When there is a long branch section on the upwind side of the tuyere and holes have been or can be punched, the air duct method can be used to determine the air volume. (Before the outlet, punch holes not less than 3 times the pipe diameter or 3 times the edge length;) 5. For rectangular air ducts, the measured section is divided into several equal small sections, each small section is as close to a square as possible, the length of the side is not greater than 200mm, the test point is located in the center of the small section, but the whole section should not be less than 3 test points; For the circular duct, the measuring section and the number of test points should be divided according to the equal-area ring method. Cut a hole in the outer wall of the air duct and insert a thermal anemometer probe or a pitot tube. (By measuring the dynamic pressure, converted to air volume.)
