Air Flow Meters
Here you will find air flow meters to measure air velocity and air pressure. Depending on the type of application, air flow meters a re made as hot-wire air flow meters or pocket weather flow meters, both of which can measure air velocity and air pressure. The results of measuring the air velocity can be stored in memory of the device depending on the model. For example, there are even data loggers for air velocity available. The total amount of our air flow meters is 34 air flow meters which can be purchased in the shop on our website. They are ideal for taking quick or constant measurements. You will find a suitable device for whatever application you desire from monitoring ventilation installations to checking wind speed for nautical enthusiasts. Air flow meters are not only available for experts and industry, but moreover also suited for schools and young people who want to learn something about wind speed, temperature and air volume. Accessories are also available along with ISO calibration certificates for these instruments (information: calibration of air flow meters). Here you will find a table with wind velocities and an approximate classification.

(Conversion information for units used by air flow meters).

General information with a link for each example of typical flow meter units of measurement: Air flow meters serve to measure wind velocity. The standard of measurement for wind velocity is at an altitude of 10m, as ground level wind velocity varies considerably for each different location. The measurement is taken according to the type of flow meter, for example, thermal measurement (hot wire air flow meters), measurement by cooling a hot wire, mechanical measurement (side wheel air flow meters) or by pressure (Pitot tube air flow meters). The final method is by ultrasound. This class of flow meter is currently too expensive in relation to it being cost effective for taking standard measurements. Many flow meters show the reading directly on their display. In this way, complicated conversion calculations are integrated to allow for a margin of error to be determined for air current velocity or for continuous air flow. Please keep in mind that when using an anemometer, the sensor (the side wheel, the hot wire probe, or the Pitot tube) is aimed towards the air current and above all that it is maintained in the direction of the flow of air. Ensure that the area is clear around the sensor to allow for the most accurate readings. Many flow meters have direction arrows. Read the user's manual to ensure that the flow meter is being used correctly, if it is not used properly, there is a risk of damaging the sensor wheel if it is not facing the airflow correctly as the impeller functions in only one direction. When using the hot wire anemometer, you must ensure that the air flow does not contain dust as the particles will impact with the sensor which is very sensitive. As the sensor is the most important part of the flow meter, if it is damaged, the device will be useless. For this reason, use the flow meter with impeller in light environmental conditions up to an air velocity of 5m/s. For greater velocities, it is recommended that you use the Pitot tube flow meter as they are very accurate, durable and have a very high measurement range.
