Abstract

The invention relates to a turbofan flow sensor and belongs to the technical field of flow measuring devices. The turbofan flow sensor comprises a casing (1), a Hall-effect switch (2), a turbofan rack (3), a steel ball (4), a turbofan (5), a shaft lever (6) and a bearing (7). According to the invention, the flow sensor which is designed by adopting the turbofan is determined to have a relatively stable friction coefficient and abrasive resistance at different angles within a range of 360 degrees due to the design of the structure and the parameters, and the flow measuring repeatability and consistency are ensured.

Description

technical field [0001] The invention belongs to the technical field of flow measurement devices, and in particular relates to a turbofan flow sensor. Background technique [0002] Impeller flowmeters mainly include turbine flowmeters, split rotor flowmeters, and water meters. However, the instruments are greatly affected by the distortion of the incoming flow velocity distribution and swirling flow. The upstream and downstream of the sensor require a long straight pipe section, which limits the space constraints The accuracy of the lower flow measurement, such as the application of measuring the cooling pipeline flow in the real vehicle state. Contents of the invention [0003] (1) Technical problems to be solved [0004] The purpose of the present invention is to solve the problem that in the existing flow measurement technology, due to the limited space of the equipment or the site pipeline, it is impossible to provide a long enough straight pipe section for the convent...
