What should be noted during the installation process of the anemometer?
The anemometer is used to measure instantaneous wind speed and direction, with automatic display function. It mainly consists of a support rod, a wind vane, a wind cup, and a wind speed and direction sensor. The direction of the wind vane is the direction of the incoming wind, and the wind speed is calculated based on the speed of the wind cup.
Wind speed measurement uses a low inertia wind vane component as the sensing component. The wind vane component rotates with the wind, driving the wind direction code disk at the lower end of the shaft. This code disk is encoded with 8-bit Gray code for photoelectric scanning and outputting pulse signals. A wind direction sensor is an instrument used to measure the horizontal direction of wind. It has a wide range of applications, such as meteorological stations, ships, oil platforms, environmental protection, etc. The instruments for measuring wind direction and wind speed include wind direction anemometers, wind direction and wind speed monitors, and other wind direction and wind speed instruments. During the installation process, the following points should be noted:
The site selection of the device is usually used for wind measurement instruments. Reasonable selection of the device site is very important, and the specific requirements are as follows:
(1) The distance between the wind measuring instrument and the obstacle should be at least ten times the height of the obstacle itself. If this requirement cannot be met, the wind measuring instrument should be placed approximately 6-10 meters above the obstacle.
(2) When it is necessary to install the wind measuring instrument on the roof, it should be installed in the center of the flat roof, not against the side device, to avoid any directional influence
In the process of using the instrument, if used properly, the instrument does not require maintenance, but severe pollution will cause blockage between the rotating and stationary parts of the instrument, so regular dirt is necessary. Due to the long-term use of the instrument causing bearing wear and affecting its performance, the instrument can be returned to the factory for maintenance.
Due to the fact that the anemometer is an on-site instrument, the environmental conditions during use differ significantly from those in the laboratory. According to the working principle of the instrument, before calibration, the rotation axis of the wind speed sensor and the coupling device of the wind speed sensor need to be connected with a hose, and the rotation axis of the sensor must be strictly concentric with the rotation axis of the instrument. If there is eccentricity between the upper, lower, left, and right after installation, the rotation torque of the coupling device cannot be fully transmitted to the rotation axis of the wind speed sensor, which can easily cause inflexibility in rotation and bring errors to the measurement results. Therefore, it is necessary to repeatedly adjust its concentricity during installation, and then start calibration work after adjustment.
