Luchtsnelheid meten - thermische anemometer in de praktijk
De luchtsnelheid is een waarde die op veel gebieden een rol kan spelen. De focus is hier met name gericht op de waarden in een ventilatiekanaal, maar ook in ruimtes kan het zinvol zijn, de luchtsnelheid te meten. Hier is het handig om een anemometer in te zetten.
Anemometers worden ook wel windsnelheidsmeters genoemd. U kunt er echter in de meeste gevallen niet alleen de windsnelheid, maar ook het debiet mee meten. Sommige anemometers hebben een geïntegreerde debietmeter.
De luchtstroom en het debiet in een ruimte zijn van invloed op de kwaliteit van de omgevingslucht. Omdat het hierbij gaat om factoren die meestal op het eerste gezicht niet herkenbaar zijn, is een regelmatige meting des te belangrijker.
Als u overweegt een thermische anemometer te kopen, dan zijn de volgende eigenschappen erg handig:
Verschuivende gemiddelde waarde berekening
Combinatie van de meting van temperatuur, stroming en debiet
Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, volume flow and air temperature in ventilation ducts
Convenient: integrated telescope that can be extended to 0.85 m, with scaling, makes it easy to carry out measurements
Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, humidity and temperature in ventilation ducts or at ventilation outlets
Clever: hot wire probe with telescope (0.85 m) – combine the vane probe (Ø 100 mm) with Bluetooth with the telescope for ceiling outlets or the funnel set for plate outlets (please order separately) as required
Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, differential pressure, humidity and temperature in ventilation ducts or at ventilation outlets
Space-saving: simply combine the universal Bluetooth handle with the 100 mm vane or hot wire probe head and the extendable telescope (1.0 m)
Measuring wind speed – the influence of air flows on indoor air quality
The measurement of wind speed is not just an interesting factor in the outdoors in terms of finding out more about the ambient conditions. The wind speed meter is now also more and more frequently used indoors. In this context, it is referred to as a thermal anemometer.
The vane anemometer is very commonly used in this area. This instrument has a probe head which can be employed to measure the airspeed and volume flow. Temperatures of up to 140°C can occur with a model that is suitable for the measurement of high temperatures and the anemometer will continue to carry out accurate measurements.
Some of the instruments which you can purchase from Testo have a permanently installed probe for flow measurement. These instruments are for instance used to enable a function test to be performed on ventilation and air conditioning systems. Flow velocities develop in a ventilation duct. Checking these flow velocities is an important factor in terms of testing whether there may possibly be a negative influence on the indoor air quality. Measurement of the flow velocity using a thermal anemometer also enables calculation of the volume flow.
Wind measurement is for instance carried out with an anemometer inside rooms when there are uncertainties about the air flows and air temperature. The reasons for this may be structural defects or also leaky windows. In some cases, the flows are so small that they cannot always be identified immediately. However, they can be quickly detected by using an instrument as sensitive as the anemometer.
A thermal anemometer has the following advantages:
Nowadays, it may be particularly helpful to use an anemometer which also has a smartphone connection. This makes analysis and reception of the values considerably easier. You can order a thermo anemometer with smartphone operation from Testo.
The model is able to measure volume flows and temperatures, as well as airspeed. The measuring values themselves are then sent to an App. This enables you to obtain the values directly and analyze them, as well as comparing them to other measurements.
A flow meter or a wind speed meter that has a connection to a smartphone also ensures that it is easier to carry out measurements in ventilation ducts in particular. The Apps which are available for the instruments are also very easy to use and have an intuitive user interface.
The advantages of a thermo anemometer with smartphone connection at a glance:
forwarding of measurement data to the App
direct analysis of the data in the App
easy handling
Buying a wind meter from Testo
If you want to buy a wind speed meter, you will find a selection of different models at Testo. Classic anemometers for the measurement of air flows are also included, along with pure flow meters or combination instruments, which can also be used to measure temperatures.
The thermo anemometer has a variety of fields of application. They benefit from easy handling and fast transmission of values. If you would like even easier analysis, you can also decide on a model with a smartphone connection.
Wind speed meter – various versions
Wind measurement can be carried out using a variety of instruments. The volume flow hood is also one of these. However, this instrument is designed primarily to enable readout of the volume flow. It was developed for use at ceiling outlets and can carry out precise measurements.
It is easy and convenient to operate. It is possible to create a report with the help of an App.
In addition to volume flow, it also measures relative humidity and temperature. Efficient results can therefore be achieved in combination with a wind speed meter, which deals with air flows.
Measuring wind speed with the vane anemometer
It is once again interesting to look at the vane anemometer as a flow meter and as a measuring instrument for airspeed. This instrument is also ideally suited for wind measurement outdoors. Testo therefore offers designs which enable you to carry out measurements quickly and easily on ventilation grilles. Here, you also get the option of measuring the air temperature and airspeeds as well. The calculation of different parameters is offered. This can also be done simply at the touch of a button on the wind meter.
