Two parts which form a device and are joined together according to the related art are joined in a complex manner and require additional elements to produce a tight joint. A device () is described which has two parts (), has welding pockets () which are capable of receiving material during the welding operation for producing a joint.

Device consisting at least of two parts joined together

A device includes a sensor carrier, on which is arranged a sensor element introduced into the flowing medium. The sensor carrier is produced separately, and the at least one sensor element may be inserted immediately into the sensor carrier. For example, the sensor carrier is mounted on a component of the device by adhesive.

Device for determining at least one parameter of a flowing medium

A device for measuring at least one parameter of a medium flowing in a line, particularly the intake-air volume of an internal combustion engine. Liquid particles contained in the line act upon a measuring element and influence a characteristic curve of the measuring element which is used to determine parameters of the flowing medium. The characteristic curve of the measuring element can be changed disadvantageously by solid-matter particles. In order to reduce the action of solid-matter particles on the measuring element, a protective grating is proposed in which side walls of channels of the protective grating form various angles of intersection with the flow direction. Solid-matter particles are thereby diverted into a path of motion around the measuring element.
