Overview
The BBFM-Q15K is a wetted ultrasonic flow measurement transducer operating at a nominal 15 kHz. Typical industrial uses include liquid flow meters, pipe velocity measurement, water-treatment flow monitoring and embedded flow modules. The standard reference range is 1500 m. Key environmental ratings: -40 to +80°C, pressure up to 10 kgf (1 MPa) and IP68 protection.

Documented acoustic-field configurations

• 15 kHz ±5% — horizontally omnidirectional acoustic field — pressure rating ≤3 kgf or 0.3 MPa
• 15 kHz ±5% — 129° ±10% half-power angle at -3 dB — pressure rating ≤10 kgf or 1 MPa
• 15 kHz ±5% — 22.8° ±10% half-power angle at -3 dB (standard) — pressure rating ≤10 kgf or 1 MPa

System integration considerations
Choose the acoustic-field variant and pressure rating to match the liquid path and installation constraints. Verify required range, target geometry, mounting space and interface dimensions against the dimensional drawing before finalizing the mounting arrangement. Drive and receive electronics must support the specified electrical parameters.
