Multi-point uniform speed type flow measuring device

The utility model belongs to the field of pipeline flow measurement, particularly relates to a multi-point uniform-speed type flow measurement device, and aims to solve the problems that the conventional measurement device cannot meet the installation requirements of large and medium-sized pipelines, the flow measurement is unstable after installation, and a wing type measurement device is inconvenient to install and maintain, large in pressure loss and high in measurement precision. In order to solve the problems that the flow is not stable enough, the output differential pressure value is small, the system sensitivity is low, a pressure tapping hole is easy to block and the like when a straight pipe section is insufficient, the utility model provides the following scheme: the Ba flowmeter comprises a positive pressure measuring unit, and the positive pressure measuring unit comprises a first welding flange welded on the surface of a pipeline to be measured. The pipeline flow measuring device is simple in st
