Flow meter / anemometer – use in numerous areas

There are different designs of the flow meter. It is also available as an anemometer and can be used in a variety of areas. There are thus some sectors, particularly in the industrial field, where flow measurement plays an important role. In addition to duct measurement, these also include outlet measurement and filter measurement.

Whether you use a vane anemometer or a volume flow hood as a flow meter is dependent on the conditions. It is all the more important for you to have a look at the individual instruments for flow measurement and to decide which of the models best meets your expectations.

The flow meter is a great help in these areas:

  • duct measurements
  • outlet measurements
  • comfort level measurements
  • filter measurements

Flow measurement – this is where it is particularly important

A detailed look at the fields of application is helpful when it comes to deciding which flow meter is suitable. They are particularly frequently used for duct measurement. Here they are used to enable airspeed to be controlled in the duct. The ventilation duct is one of the most important core elements of air conditioning and ventilation systems. The use of flow meters is also a solution to enable the function to be controlled in this area.

However, it is not only air conditioning systems that need to be efficient. This aspect should not be underestimated when it comes to duct outlets either. Outlet measurement is therefore another factor which needs to be taken into account in terms of flow measurement. The anemometer can be a particularly great help in this respect. Even small changes in volume flow can affect the system.

The influence of airspeed on the ambient conditions in different rooms is underestimated. The comfort level that a person experiences in a room is heavily dependent on the environment. Temperature and humidity, as well as airspeed, have an influence on this. A thermal anemometer is particularly frequently used in these areas. However, the vane anemometer may also be a good choice in terms of obtaining effective values.

Flow measurement

In relation to flow measurement, it is worth going back to air conditioning systems again. Air conditioning systems are equipped with a filter. Regular control is advisable to ensure their optimum operation. Filter measurement can be carried out using an anemometer. This is the only way to prevent dirt from being able to find its way inside through the filter and harming the indoor air.

The following are anemometers for measuring flows and other values:
