Wing wind measuring device is at present, domestic electric power industry primary and secondary air flow measurement in the use of the most extensive of a flow measuring device, it and other measuring device compared with the following advantages:

A, has a unique wing type, can produce a large differential pressure, measurement stability.

B, the use of two wing or multi wing structure, the device itself is short, and the need to lower straight pipe section.

C, the pressure loss is small, the pressure loss is not more than 14% of the differential pressure value.

D, the flow is uniform and stable, the fluid has a certain role in the rectification.

E, easy installation and maintenance.

F, high accuracy, the maximum flow of 30 to 100% range, the error is not more than 2%.
