A brief explanation of the steps involved in operating an anemometer
An anemometer is an instrument that measures the speed of air flow. There are many types of it. The commonly used wind cup anemometer in meteorological stations is the wind cup anemometer. It consists of three parabolic cone empty cups fixed on the bracket at an angle of 120° to each other to form the sensing part. The concave surfaces of the empty cups all face one direction. The entire sensing part is installed on a vertical rotating axis. Under the action of wind force, the wind cup rotates around the axis at a speed proportional to the wind speed.
Anemometer operating steps:
1. Observe whether the pointer of the meter points to zero before use. If there is 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 measuring rod plug into the socket, place the measuring rod vertically upward, tighten the screw plug to seal the probe, place the "calibration switch" in the full-scale position, and slowly adjust the "full-scale adjustment" knob to make the meter pointer point in the full position;
4. Set the "calibration switch" to the "zero position" and slowly adjust the "coarse adjustment" and "fine adjustment" knobs so that the meter pointer points to the zero point;
5. After the above steps, gently pull the screw plug to expose the measuring rod probe (the length can be selected according to your needs), and make the red dot on the probe face the wind direction. Check the calibration curve according to the meter reading. Find out the measured wind speed;
6. After measuring for several minutes (about 10 minutes), the above steps 3 and 4 must be repeated once to standardize the current in the meter;
7. After the measurement, the "calibration switch" should be placed in the off position.
Anemometers can be widely used in various fields, such as electric power, steel, petrochemicals, energy conservation and other industries. In daily life, many industries need to use anemometers, such as fan manufacturing, fishing industry, exhaust exhaust heating systems, etc. An anemometer is needed to measure wind speed, wind temperature, and air volume to ensure normal operation.
