Brief explanation of the operating steps of the anemometer
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.
Operation steps of anemometer:
1. Before use, observe whether the pointer of the meter points to zero. If there is any deviation, gently adjust the mechanical adjustment screw of the meter to return the pointer to zero;
2. Place the calibration switch in the off position;
3. Insert the plug of the measuring rod into the socket, place the measuring rod vertically upwards, press the plug tightly to seal the probe, place the "calibration switch" in the full degree position, and slowly adjust the "full degree adjustment" knob to make the meter pointer point at the full degree position;
4. Place the "calibration switch" in the "zero position" and slowly adjust the "coarse adjustment" and "fine adjustment" buttons to make the meter pointer point at the zero position;
5. After the above steps, gently pull the plug to expose the probe of the measuring rod (length can be selected according to needs), and make the red dot on the probe face the wind direction. Based on the reading of the electricity meter, refer to the calibration curve to find the measured wind speed;
After measuring several points (about 10 minutes), the above steps 3 and 4 must be repeated once to standardize the current inside the instrument;
7. After the measurement is completed, the "calibration switch" should be placed in the off position.
Anemometers can be widely used in various fields, such as power, steel, petrochemical, energy conservation, and other industries. In daily life, many industries require anemometers, such as fan manufacturing, offshore fishing, and exhaust heating systems, to measure wind speed, temperature, and volume to ensure normal operation.
