The invention relates to a flow measuring device, in particular to an insert flow measuring device based on an MEMS sensor, which is formed by a measuring tube, a probe, a fixing device, a secondary instrument, a high pressure tapping, a low pressure tapping and an MEMS sensitive core body of the sensor portion, an encapsulating structure and a signal wire, wherein the MEMS sensitive core body isarranged inside the probe, the pressure tapping is located in the measuring tube, and the structure for guiding pressure to the outside of the tube in a traditional insert flow meter is omitted. The dynamic and stable measurement for the flow is realized according to a flow-pressure difference mathematic relation and actual calibration in the field. The invention solves the problems existing in atraditional insert flow meter of poor dynamic characteristic, large error and high loss and the like.
