Introducing the UIM 4F DUO

blank

The UIM-4F DUO consists of two fully independent measurements in a single flow body. The UIM 4F DUO is available in 4 + 3 version as well as a 4 + 4 version at a lower price than our competitors’ 4 + 1 and 4 + 2 units. In the 4 + 3 version the main measurement is done by the UIM-4F four path and the secondary measurement by the UIM-3 path. The four path measurement is certified to OIML R 137 (class 0.5). By using a three path secondary measurement, the UIM-4F DUO provides the diagnostics needed to detect potential issues. Our competitors typically use only a single path or dual path for their secondary measurement, which does not have the sensitivity to detect small profile changes.

The 4 +4 version provides two fully independent measurements with custody transfer accuracy certified to OIML R 137 (class 0.5). For more information visit our Products Page or download the information leaflet.
