The invention provides a high temperature resistant sensor for a flowmeter. The high temperature resistant sensor comprises a base, a dowel bar, a deformable body connected between the base and the dowel bar, a strain gauge fixedly arranged at the upper part of the base and provided with a deformable part, and an oscillation lever, wherein the lower end of the oscillation lever is fixedly arranged on the dowel bar, the upper end of the oscillation lever passes through an avoiding hole of the deformable body and a central hole of the base, and the oscillation lever is in contact with the deformable part of the strain gauge; when the oscillation lever swings along the dowel bar, the deformable part of the strain gauge can be driven to perform corresponding deformation. The high temperature resistant sensor is simple in structure and convenient in assembly; the strain gauge is arranged at the upper part of the base and can be prevented from being damaged due to the action of high temperature in high-temperature fluid.
