These anemometers are often applied for stationary wind measurement and wind monitoring.Ī special design of the anemometer is the Pitot tube anemometer. Anemometers of this type are used when the wind or a flow should be measured regardless of the direction. Thus, it is not possible to measure very small wind speeds with vane anemometers.Īnother type of the moving anemometers is the cup anemometer. This initial flow is often between approx. A disadvantage is that a certain wind speed is required till a measurement is carried out. A significant difference compared to the hot wire anemometers is that here the moving parts are needed to measure the wind. Depending on the model, the actual measurement takes place then via a Hall sensor which registers the individual revolutions, or via an optical sensor, which scans a reflex mark attached to the impeller. In contrast to the hot wire anemometer, this wind meter has a wheel, which is driven by the wind. Other anemometers used to measure directional flows are the vane anemometers. The measurement with a thermal anemometer is often a measurement for directed flows. Thermal anemometers are often used to measure the draft flow or to measure flow velocities in ducts. In thermal anemometers, the temperature is often also measured by means of a separate sensor element. By measuring the electrical variables of current and voltage, the resistance at a corresponding flow velocity can be calculated. If a wind flows past the sensor element of the anemometer, this resistor cools down. In case of a thermal anemometer, also referred to as a hot wire anemometer, an electrical resistor with a defined current and a constant voltage is heated. When selecting an anemometer, the design and the measuring principle are primarily in focus.įor exact measurements of small wind speeds, the thermal anemometers are often used.

PCE Instruments is also happy to develop individual measurement solutions for wind monitoring for special applications.
