Wind Measurer for Measuring Wind Speed

Information about the Wind Measurer
The PCE-A420 is a Wind Measurer for measuring wind speed. The three horizontally aligned spherical cups, which are fixed crosswise or in a star shape on the vertical axis of the Wind Measurer, record the wind speed during a measurement. The measuring principle is simple: the stronger the wind blows, the faster the half-open plastic cups turn. The speed of the cross rotation determines the wind speed.
This PCE wind flow meter, also referred to as the Wind Measurer, offers a significant advantage in comparison to the standard impeller anemometers. The wind direction is not of crucial importance in the measurement of the flow rate. In order to be able to measure the wind speed accurately, the Wind Measurer, in contrast to the impeller anemometer, does not have to be kept exactly in the wind direction. The orientation of the half-cups in different directions ensures that the cup star is set in motion independent of the direction. Thus, the smooth and light cup-cross reacts to even the smallest flow velocities. With a resolution of 0.1 m / s or 0.1 km / h, the measuring range of the Wind Measurer is from 0.9 m / s up to 35 m / s or from 2.5 km / h up to 126.0 km / h. There are different units for the flow velocities with m / s, km / h, knots, miles / h, ft / min available.
The Wind Measurer records the number of rotations per minute and thus the wind speed very accurately. The wind speed can be conveniently read out via the LC display (28 x 19 mm) of the Wind Measurer. The anemometer of PCE Instruments stores maximum and minimum values, which can be conveniently read again on the display later. To ensure that the last measurement results displayed can be viewed again, the Wind Measurer also has a practical Data-Hold function. The measurement data are recorded and stored via a useful 100-point data logger. The Wind Measurer is marked IP 65, meets all the conditions and is thus protected against the penetration of dust and moisture. To save the battery of the Wind Measurer when not in use, the meter is equipped with an Auto-Power-Off function. After a short while, the Wind Measurer turns off by itself.
Applications
Due to its compact plastic housing, its handy size and its low weight of just 180 grams, the cup-anemometer PCE-A420 offers maximum mobility and flexibility. The Wind Measurer can be used wherever the mobile wind speeds need to be measured. At the place of application, the Wind Measurer allows accurate wind speed measurements of up to 35 m / s. This anemometer is indispensable wherever fast and precise wind speeds close to the ground have to be checked. Because of its simple operation, the Wind Measurer is also suitable for collecting the weather data for private use. In the meteorological field, for better international comparability, the wind speed is measured 10 meters above the ground. For such applications, stationary systems, which record not only the wind speed but also some other weather parameters such as the wind direction, are suitable. Also for such stationary applications, PCE Instruments, as a manufacturer of measuring technologies, has suitable anemometers in the range of products.
What is a Wind Measurer?
"Ánemon" is a Greek word for wind. An application of anemometer is the measurement of the wind speed. Most commonly, the Wind Measurer is used. The airflow meter has a vertical axis and three or four egg-shaped half-cups that take in the wind.
Measuring principle
The faster the wind blows, the faster the open cups turn. The number of revolutions per minute is recorded electronically. If one counts the revolutions in a second or minute, one has a measure for the speed of the wind. Mostly there is a Wind Measurer in connection with a wind direction sensor, mounted on a frame, as a fixed measuring unit. The air flow meter PCE-A420 enables mobile measurements of the wind speed of up to 35 m / s directly at the place of application.
