CFJD25 (A) type (B) series mechanical and electronic wind speed meter for coal mine is a new generation of intelligent digital wind speed and air volume detection instrument. It is mainly used for the measurement of instantaneous wind speed, average wind speed and average wind volume. This wind meter is a high-precision wide-range precision anemometer, which combines high speed, medium speed and micro speed three speeds into one. Automatically correct the non-linearity of the three ranges, the corrected data is more accurate. When measuring the average wind speed using the sweep mode line method for overall measurement, the user enters the m2 value of the measured cross-sectional area, after measuring the time-averaged wind speed, directly Press the alternate air volume key to read the air volume flow m3 value directly.
