Horizontal omnidirectional response for wind measurement
The BBFM-V192K is an ultrasonic transducer for 2D and 3D anemometers, meteorological monitoring, ventilation airflow measurement and industrial duct monitoring. Its center frequency is 192 kHz ±5%, and the specified reference range is 0.10 to 1.5 m.
The acoustic field is horizontally omnidirectional. This response should be considered with the required acoustic path and transducer arrangement when building a wind speed and direction measurement system.

Electrical and mechanical integration
Match the transmit and receive electronics to a minimum impedance of 50 Ω ±20% and capacitance of 7500 pF ±20% at 1 kHz. Peak voltage must remain below 250 Vpp.
Use the dimensional drawing to confirm the mounting interface and acoustic arrangement. The installation should operate between -40 and +80°C and at no more than 3 kgf or 0.3 MPa while retaining IP68 protection.
