Acoustic level sensor for solids with 3D surface mapping BinMaster

The BinMaster 3DLevelScanner utilizes a 2-dimensional array beam-former that sends very low frequency, dust-penetrating acoustical pulses and receives echoes of the pulses from multiple points on the surface of the material in the bin. The 3DLevelScanner offers multiple point accuracy as the device takes measurements from multiple points versus a single point, thereby taking into account variations that can occur on material surfaces. Standard ultrasonic, radar or cable-based units measure just one point and determine a single distance, while the 3DLevelscanner takes measurements from multiple points within the bin, ensuring greater accuracy.

The low frequency technology penetrates dust, making it suitable for environments where ultrasonics and radar may fail. It is unaffected by material type and is appropriate for powders, granulates, pellets and other solids with no need for special calibration. Employing non-contact measurement, it is suitable for foods, chemicals and pharmaceuticals. There is no risk of moving parts coming into contact with bin material. It offers long measurement range of up to 220 feet and is appropriate for tall bins (taller than they are wide). Three independent transducers promote accuracy and system redundancy, making it one of the most advanced technologies available.

The 3DLevelScanner provides the user a scaled 4-20mA output that can represent either the product or headroom volume. Using an optional HART or RS-485 connection, the user can also connect to the scanner using the 3DLevelManager software. This advanced software allows the user to view real-time data from the scanner and make configuration changes remotely from a PC.
