3-axis ultrasonic anemometer BBUAM-3D

IP65wirelessdigital

Product overview
The BBUAM-3D is a complete ultrasonic instrument for real-time measurement of three-dimensional wind speed, wind direction, air temperature and speed of sound. Without mechanical rotating parts it is immune to mechanical wear or inertia and measures both horizontal and vertical air motion. The instrument integrates a 3D measuring frame, ultrasonic transducers and onboard signal processing; data output supports RS485, RS232, analog and optional wireless interfaces for long-term continuous monitoring.
