Abstract

Laitteisto ja menetelmä ilmavirtauksen mittaukseen kanavassa, esimerkiksi ilmanvaihtokanavassa (300), joka laitteisto käsittää ohjausyksikköön liitettävissä olevat välineet kanavan ilman virtausnopeuden ja/tai virtaussuunnan mittaukseen. Laitteisto edelleen käsittää kanavan yhteyteen järjestetyt välineet etäisyyden mittaukseen. Laitteisto on sovitettu mittaamaan kanavan tai sen osan koko välineillä etäisyyden mittauksen. Laitteisto on edelleen sovitettu tallentamaan ja/tai lähettämään kanavan kokoon liittyvä tieto laitteistoon, ohjausyksikköön ja/tai laitteistoon liitettävissä olevaan ohjausyksikköön.Apparatus and method for measuring airflow in a duct, for example a ventilation duct (300), comprising means for measuring a duct air flow rate and / or a flow direction which can be connected to a control unit. The apparatus further comprises means for measuring the distance arranged along the channel. The apparatus is adapted to measure distance measurement by means of the whole or part of the channel. The apparatus is further adapted to store and / or transmit channel size information to the hardware, control unit and / or control unit that can be connected to the apparatus.
