Abstract
The invention relates to a thermal type flow meter. The flow meter comprises a base part with at least two through bores extending substantially parallel to each other. A flow tube for the medium whose flow is to be determined is provided through the through bores. A part of the flow tube spaced from the base part comprises a measuring tube part where the flow of the medium can be measured. The flow measuring tube comprises an insulating housing connected to the base part, which surrounds at least the measuring tube part of the flow tube. The insulating housing comprises an inner housing surface, which faces the measuring tube part, as well as an outer housing surface, which faces away from the measuring tube part. According to the invention, a cover element connected to the base part is provided, which cover element at least substantially surrounds the insulating housing.
