Patent ID: 8491184

Claim:
A multi-fluid flow path containing a sensing system for sensing subject media comprising: a sensor manifold comprising a housing enclosing at least a first fluid flow path and a second fluid flow path which are fluidically isolated from each other during use of the sensing system, each of said first and second fluid flow paths having a fluid inlet port and a fluid outlet port; and a sensor apparatus for sensing conductivity of subject media in each of said first and second fluid flow paths, wherein the sensor apparatus comprises a separate group of conductivity sensors associated with each of said first and second fluid flow paths, each group of conductivity sensors comprising at least two conductivity sensing probes spaced apart from one another, wherein the sensor manifold comprises a top plate and a base, the top plate being sealingly engaged with the base to define the volumes of the fluid flow paths, wherein the sensing probes penetrate the top plate to extend into the fluid flow paths.
