    What are the Anemometers Used for?

    An anemometer is an instrument used to measure the speed or velocity of gases either in a contained flow, such as airflow in a duct or in unconfined flows, such as atmospheric wind. To determine the velocity, an anemometer detects changes in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the flow.

    12 Tips for Using Wind Meter

    A wind Meter (Anemometer) is an instrument for measuring airflow speed, which can be widely used in various fields, such as electricity, steel, petrochemical, energy-saving and other industries, in daily life, many industries need to use the wind anemometer, such as fan manufacturing, sea fishing industry, extraction and exhaust heating systems, etc., are required to use the anemometer for wind speed, wind temperature, wind measurement to ensure normal work.

    How to Choose the Anemometer Probe?

    The flow velocity measurement range from 0 to 100 m/s can be divided into three zones: low velocity: 0 to 5 m/s, medium velocity: 5 to 40 m/s, high velocity: 40 to 100 m/s. The anemometer's thermal probe is used for measurements from 0 to 5 m/s; the anemometer's rotor probe is most effective for velocities from 5 to 40 m/s; and the use of a pitot tube gives the best results in the high velocity range. An additional criterion for the correct selection of an anemometer flow probe is the temperature, which usually reaches about +-70°C for thermal sensors. Special anemometers have runner probes up to 350C. Pitot tubes are used above +350°C.

    4 Anemometer Types For Measuring Wind Speed

    The wind speed test has the test of average wind speed and the test of turbulence component. The thermal anemometer is to test the average wind speed. The methods of testing the average wind speed are thermal, ultrasonic, impeller, and skin dragging tube, but in these methods, the anemometer is using the principle of heat dissipation. Below, a description of these types of anemometers is given.

    How to Use a Wind Anemometer?

    ATO anemometers are used in health supervision, environmental monitoring, health and epidemic prevention, university academies, food safety, industrial pollution, heavy metal dyes, potions, chemicals, beverages, bacteria, sewage, pulp, pharmaceuticals, fermentation, electroplating, drinking water production workshops, Planting, breeding and fishing sites. Here's how to use an wind anemometer and its precautions:

    Wind Meter Basics & Working Principle

    The wind meter (anemometer) is an instrument that measures the speed of wind. To determine wind speed, wind meters detect changes in certain physical properties of the fluid or the effect of the fluid on a mechanical device inserted into the airflow. There are many types of it. The most commonly used in meteorological stations is the wind cup anemometer. Its sensing part consists of three parabolic cone empty cups fixed on the bracket at 120°to each other. The concave surfaces of the empty cups are all in one direction. The entire induction part is installed on a vertical rotating shaft. Under the action of wind, the wind cup rotates around the shaft at speed proportional to the wind speed.

    What is a 3-Cup Anemometer?

    An anemometer is an instrument that measures the speed of air. There are many types of it, and the three-cup anemometer is widely used. Robinson in the United Kingdom invented the rotating cup anemometer, and it was four cups at that time, and then it was changed to three cups. The three parabolic or hemispherical empty cups fixed to each other on the rack are all in one direction, and the entire rack together with the wind cup is mounted on a freely rotatable shaft. The three-cup anemometer commonly used in meteorological stations is composed of three parabolic cone empty cups fixed on the bracket at 120° to each other, and the concave surfaces of the empty cups are all in one direction. The entire induction part is installed on a vertical rotating shaft. Under the action of wind, the wind cup rotates around the shaft at speed proportional to the wind speed. Another type of rotary anemometer is the propeller anemometer, which consists of a three-blade or four-blade propeller to form a sensing part, which is installed at the front end of a wind vane so that it is always aligned with the direction of the wind. The blades rotate about the horizontal axis at a speed proportional to the wind speed.
