The invention provides an embedded turbine flowmeter, and particularly relates to a turbine flowmeter which is applicable to the measurement of fluid in an intensive pipe bundle. The turbine flowmeter is characterized in that: the wall of the shell (1) of the embedded turbine flowmeter is provided with a groove shape hole along the axial direction, a signal detector (3) is positioned inside the groove shape hole, a cavity installed with the signal detector (3) is filled with epoxy resin glue, and a machine core (2) is positioned inside the cavity of the shell (1). During the rotation process of an impeller of the machine core (2), the front end thereof can cut the magnetic line of the magnetic field of the signal detector (3); therefore, an electrical pulse signal is formed inside the signal detector and amplified by an amplifier so as to realize the measurement of the fluid. When being used, the turbine flowmeter is directly embedded into a fluid pipe, thus being particularly applicable to the measurement of the fluid in the intensive pipe bundle.
