FAQ

Find answers to common questions about the SentroPAT BU II, including installation, positioning, and system integration. If you need further details, feel free to contact our team.

How is it ensured that the system measures in the correct position?

The SentroPAT BU II is equipped with a MEMS-based position sensor that triggers measurements when material covers the measurement window, which is installed in the IBC or its lid. The measurement position can be influenced by factors such as the fill level, rotation characteristics, and rotation speed. However, in most cases, the default settings provide reliable operation. For specific scenarios, the system settings can be easily adjusted within the software.

How is the system mounted to the bin?

The SentroPAT BU II is mounted using a sanitary 4" clamp attached to a flange with a sapphire window. These flanges are designed to be welded into the IBC or its lid and are available as standard accessories. If needed, our engineering team can explore customized adaptations, such as different diameters, adapters for existing ports, or other installation-specific requirements.
