How to maintain and upkeep anemometers correctly
An anemometer is an instrument used to measure the velocity of air. There are many types of it, and the commonly used anemometer in meteorological stations is the wind cup anemometer. It consists of three parabolic cone empty cups fixed on a bracket at an angle of 120 ° each, forming an induction part. The concave surface of the empty cup is in the same direction. The entire sensing part is installed on a vertical rotation axis, and under the action of wind, the wind cup rotates around the axis at a speed proportional to the wind speed.
The anemometer belongs to the category of safety protection and environmental monitoring measuring instruments, and is a mandatory calibration measuring instrument stipulated by China's Metrology Law. In addition to the corresponding calibration report required for factory sales, it is also necessary to regularly calibrate the instruments at the National Air Conditioning Equipment Quality Supervision and Inspection Center or the Building Energy and Environmental Testing Center of the Chinese Academy of Building Sciences every year in accordance with the JJG (Construction) 0001-1992 "Verification Regulations for Hot Ball Anemometers", and adjust all aspects of the instruments to obtain good working conditions based on the statutory calibration certificate issued by them.
In addition to maintaining the accuracy of daily data, the following points should also be noted during daily maintenance and use:
1. It is prohibited to use anemometers in flammable gas environments.
2. It is prohibited to place the anemometer probe in flammable gases. Otherwise, it may lead to fire or even explosion.
3. Please use the anemometer correctly according to the requirements of the user manual. Improper use may lead to electric shock, fire, and damage to sensors.
4. In use, if the anemometer emits abnormal odor, sound, or smoke, or if liquid flows into the anemometer, please immediately shut down and remove the battery. Otherwise, there is a risk of electric shock, fire, and damage to the anemometer.
5. Do not expose the probe and anemometer body to rain. Otherwise, there may be risks of electric shock, fire, and personal injury.
6. Do not touch the internal sensor area of the probe.
7. When the anemometer is not in use for a long time, please remove the internal battery. Otherwise, the battery may leak liquid, causing damage to the anemometer.
8. Do not place the anemometer in areas with high temperature, humidity, dust, and direct sunlight. Otherwise, it will cause damage to internal components or deterioration of anemometer performance.
9. Do not use volatile liquids to wipe the anemometer. Otherwise, it may cause deformation and discoloration of the anemometer housing. When there are stains on the surface of the anemometer, a soft fabric and neutral detergent can be used to wipe it off.
10. Do not drop or heavily press the anemometer. Otherwise, it will cause malfunction or damage to the anemometer.
11. Do not touch the sensor part of the probe while the anemometer is charged. Otherwise, it will affect the measurement results or cause damage to the internal circuit of the anemometer.
