Beschreibung
Zusammenfassung:	The invention relates to a fluid flow rate measuring device (1) comprising a first opening (7) for receiving fluid, a second opening (8) for discharging at least a part of said fluid, a thermal flow rate sensor (4, 5) arranged between said first opening (7) and said second opening (8) and at least one third opening. It is proposed that the flow rate measuring device includes at least one of at least one groove (2) and at least one protrusion (3) being formed between the first opening (7) and respected once of said at least one third opening (9).
