Devices for sensing a fluid, for instance in a ventilation duct, do often have to be mounted in places where the available space is limited. Thus, lack of space is a great problem for mounting such devices.
In WO2006/078204 a device for sensing a fluid, such as in a ventilation duct, is disclosed. Even though the device in WO2006/078204 is relatively compact, there is still a need for improved sensing devices that may be mounted in limited spaces.
