  3. Flow meter – for optimum flow measurement

Flow meter

There are different designs of flow meters. It is also available as an anemometer and can be used in a variety of areas. There are 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 meters / anemometers – Ideal for a majority of flow applications

Whether you use a vane anemometer or a volume flow hood for measurement is dependent on the conditions. It is important for you to have a look at the individual instruments for flow measurement and to decide which models best meet your needs.

A Testo Flow Meter is a great help in these areas:

  • duct measurements

  • outlet measurements

  • comfort level measurements

  • filter measurements

Flow measurement – where it matters most

A detailed look at the fields of application is helpful when it comes to deciding which flow meter is suitable, as they are frequently used for duct measurements, where 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 ideal for measurements in these areas.

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 another factor which needs to be taken into account when measuring flow. An anemometer is great help in this respect. Even small changes in volume flow can affect the system.

The following anemometers are exceptional 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 – SMART Flow Measurement Instrumentation

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

A vane anemometer 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. For example, a vane anemometer is capable of timed and multi-point mean value calculations, where this may not be provided by an air velocity and IAQ measuring instrument.

Measure flow easily

Let's go back to indoor flow measurement. In this area, an anemometer is also an ideal choice to make measuring 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 be easily fitted on a ventilation duct. Additional accessories for flow measurement may be required, however you will find everything you want at Testo.
