NOVELTY - The utility model claims a flow rate sensor, comprising: graphene sensing element (1), two guide bracket (3) and a flexible carrier (2). On said flexible carrier (2) is covered on the graphene sensing element (1), two said support wire (3) respectively and the graphene sensing element (1) connected with power, and the wire to the flexible carrier out. The graphene and sensing element (1) in the flexible seal carrier (2). This new utility model providing the flow rate sensor structure is simple, suitable use, and sensing element and not directly contact fluid, can prevent the fluid to damage the sensing element.
