  3. Flow meter – optimum flow measurement

Flow meter

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.

Flow meter / anemometer – use in numerous areas

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 following are anemometers for measuring flows and other values:

Vane anemometer

For flow measurements at air outlets and in ventilation ducts as well as for checking the supply and exhaust air at ventilation grills, plate outlets and swirl outlets.

Anemometers – instruments with helpful features

Flow measurement can become a challenge if you do not have the appropriate instruments to hand. When you are searching for a flow meter, it is therefore important for you to check exactly what values will be recorded by the instrument.

A classic wind speed meter has different features from a thermal anemometer or a volume flow hood. It is possible to measure flow with various instruments. However, they are variable in terms of the specific features. So, a vane anemometer is for example capable of a timed and multi-point mean value calculation. This may not be provided by an air velocity & IAQ measuring instrument.

Measure flow easily

Let's go back to indoor flow measurement. In this area, the anemometer is also an ideal choice that can make a lot of things easier. The vane anemometer, or the addition of a vane probe to an anemometer, enables measurement of volume flow and flow rate.

The measuring ranges provide information about what the maximum strength is for flow recording. However, flow measurement can also be carried out using a differential pressure measuring instrument. This can for instance be very easily fitted on a ventilation duct and used there. You may still need additional accessories for flow measurement. Here too, you will find just what you want at Testo.
