1. Product Overview
YGM306 is a rhombic air speed transmitter capable of measuring the highest wind speed of 50 m/s. It is a rhombic average velocity measuring piece designed based on the principle of measuring the velocity with an averaging tube. According to the shape and size of the measured pipe, multiple pairs of total pressure holes can be designed on the windward side according to the specific opening principle; At the same time, on the leeward side of the average velocity measuring piece, several pairs of back pressure holes are opened, and the back pressure holes correspond to the total pressure holes one by one, so as to achieve the purpose of average velocity measurement.
