Wind warning systems complete the assortment of anemometers. These anemometers can, for example, additionally determine temperatures or flows in watercourses. In addition, there are anemometers, which can be used as a multifunction device. Furthermore, there are anemometers, which have interfaces, which make it possible to transmit the measured value to a PC. Here, as well as for many other measuring instruments from the assortment, there are many different models.įor example, there are models which merely display the flow velocity and give the user the information about the measured value. If the design and the measuring principle corresponding to the measurement task of the anemometer have been selected, the device with the correct display has to be found. These anemometers are known from racing or aircraft construction. Pitot tube anemometers are often used at very high flow velocities. The difference between the two pressures gives the flow rate. Via a special Pitot tube probe, the anemometer measures the ambient pressure in a duct and the incoming pressure that affects the probe. A Pitot tube anemometer calculates a flow velocity based on the difference between two pressures. 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. In the following text, you may find some information meant to facilitate the decision when purchasing an anemometer. Anemometers are available in many different designs and equipment variants. ![]() * Multi-function display for air flow measurement in m/s, km/hr, ft/min, MPH, Knots and temperature in deg C or FĠ deg C to 50 deg C (32 deg F to 122 deg F)ĭimensions: 198mm x 78mm x 51mm (7.8" x 3.1" x 2.An anemometer is a device, a measuring instrument for checking wind speed. * Super large LCD with backlight allows air velocity and air temperature display at the same time * Records maximum/minimum readings with recall and data hold * Combination of hot wire and standard thermistor delivers rapid and precise measurements * Slim probe, ideal for grilles and diffusers * Thermal anemometer for very low air velocity measurement It comes with a carrying case for added protection.
