The Ultimaker Flow Sensor Casing is an original replacement part designed to house and protect the flow sensor in Ultimaker 3D printers. The flow sensor monitors material throughput during printing, and a properly seated casing ensures accurate readings and stable extrusion detection throughout long print jobs.

This part is a direct OEM replacement, making it ideal for planned maintenance or reactive repairs when the casing shows signs of wear, damage, or breakage. Swapping in a genuine Ultimaker part ensures that sensor alignment and function remain within factory specifications, minimising the risk of false flow errors or missed clogs.
