How to properly maintain and service anemometer
Anemometer is an instrument used to measure the velocity of air flow. There are many types of it, and the commonly used one in meteorological stations is the wind cup anemometer. It consists of three parabolic cone empty cups fixed at 120 ° to each other on a bracket to form the sensing part, and the concave surfaces of the empty cups all face 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.
Anemometer belongs to the category of measuring instruments for safety protection and environmental monitoring, 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 instrument at the National Air Conditioning Equipment Quality Supervision and Inspection Center or the Building Energy and Environment Testing Center of the China Academy of Building Research in accordance with the requirements of JJG (Construction) 0001-1992 "Hot Ball Anemometer Calibration Regulations" every year, and adjust all aspects of the instrument according to the statutory calibration certificate issued by them to obtain good working condition.
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 instructions in the user manual. Improper use may result in electric shock, fire, and damage to sensors.
4. If the anemometer emits abnormal odors, sounds, or smoke during use, or if liquid flows into the interior of the anemometer, please immediately turn off the device 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 sensor area inside the probe.
When the anemometer is not in use for a long time, please remove the internal battery. Otherwise, the battery may leak and cause damage to the anemometer.
8. Do not place the anemometer in places with high temperature, high humidity, high dust, and direct sunlight. Otherwise, it will result in 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 when the anemometer is charged. Otherwise, it will affect the measurement results or cause damage to the internal circuit of the anemometer.
