Abstract

An in-line fuel properties measurement unit (IFPMU) (50) for in-line assembly in a fluid flow path, in particular a fuel flow path of an aircraft, includes a compensator section (58) and a densitometer section (60). The densitometer section is connected in-line with the compensator section such that full fluid flow is seen by each section. The IFPMU further includes a circuit card having tabs or “arms” for electrically interfacing with cylinders of the compensator section, wherein the cylinders include reliefs formed therein to create an air gap between the cylinder and the tab.
