How to Properly Maintain and Maintain Anemometers
An anemometer is an instrument that measures the flow rate of air. There are many types of it, and the commonly used anemometer in meteorological stations is a wind cup anemometer. It consists of three parabolic cone empty cups fixed on a bracket at an angle of 120 ° to each other, and the concave surface of the empty cup is in the same direction. The entire sensing part is installed on a vertical rotating axis, and under the action of wind, the wind cup rotates around the axis at a speed proportional to the wind speed.
Anemometers belong to the category of safety protection and environmental monitoring measuring instruments, and are mandatory calibration measuring instruments 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 instrument at the National Air Conditioning Equipment Quality Supervision and Inspection Center or the Building Energy and Environment 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 instrument according to its statutory calibration certificate to obtain good working conditions.
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 cause a fire or even an explosion.
3. Please use the anemometer correctly according to the requirements of the user manual. Improper use may lead to electric shock, fire, and sensor damage.
4. In use, if the anemometer emits abnormal odor, sound, or smoke, or if liquid flows into the interior of 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 part 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 the performance of the anemometer.
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.
10. Do not drop or press the anemometer heavily. 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.
