Ultrasonic wave wind speed indicator

The utility model discloses an ultrasonic wave anemoscope which comprises a base, a control circuit board, four measuring arms and four ultrasonic wave emitting/receiving probes. The four measuring arms are respectively connected with the base and form 90 degrees angles between every two adjacent measuring arms sequentially; the four ultrasonic wave emitting/receiving probes are respectively mounted on ends of the four measuring arms far away from the base; meanwhile, two pairs of probes are in opposite in the same horizontal plane, form 180 degrees angles and have equal vertical distances with the base. A heater can be arranged in the measuring arm of the ultrasonic wave anemoscope; correspondingly, a temperature control circuit and a heating circuit are mounted on the control circuit board. The ultrasonic wave anemoscope has the advantages of solving the technical problem that the measuring information is obtained by the operating part, improving the measuring accuracy at the same time, extending the servic
