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.

Gobius is installed and ready to use in 30 minutes!
Gobius is the first level indicator in the world that measures the contents of tanks in stainless steel, steel, aluminum, plastic and fibre glass from the OUTSIDE. Gobius is reliable, regardless of the tank’s size, shape, or amount of deposit on the inside of the tank wall. Level indication conducted from the outside of the tank means contact free measurement. The advantages of this is highly appreciated by the pharmaceutical, chemical and food industries, where demands on handling of corrosive and sterile liquids are very high.
Very easy to calibrate
No tanks look the same. There are always differences in e.g. size, construction, thickness and age. In order to compensate for these differences you have to calibrate the tank before you start to use your Gobius. However, the calibration only takes a few seconds, all you need to do is to press a button while the tank is full or empty.
The Gobius Technology (patented)
Level indicator Gobius is based on our innovative Gobius Technology, best described as ”knock and listen”. Every sensor that is placed onto the tank wall consists of a shaker and an accelerometer. When the shaker creates a vibration in the tank wall, the accelerator measures the size of the vibration and passes the data on to the control unit. Each sensor is only 26 mm high with a diameter of 70 mm.
Complete system
On the sensors there are strips of tape that are provided to attach the sensors directly onto the surface of your tank. All necessary cables and plugs needed to connect the sensors and panel with the control unit and to external systems are included.
