Flow sensor for automatically measuring oil quantity

The utility model provides a flow sensor for automatically measuring oil mass, which relates to the technical field of flow sensors and comprises a metal tube, a front flow guide part and a rear flow guide part are fixedly mounted on the inner surface wall of the metal tube, and a turbine is movably arranged between the opposite sides of the front flow guide part and the rear flow guide part. The outer surface wall of the metal pipe is fixedly sleeved with a first sleeve, when the device breaks down and needs to be replaced, a motor is started, a baffle can be driven to rotate, in this way, a channel of an oil pipe can be blocked by the baffle, oil leakage is prevented, at the moment, a first enamel disc can be detached from a second enamel disc, and the device is convenient to use. And then the device which breaks down is maintained or replaced, and then the device is installed back to the original position, so that the device can be disassembled and replaced without pausing the oil conveying pipeline. 本实用新型
