Fluidix, Inc. offers a true-union gauge isolator to permit direct connection to virtually any high purity piping system. Available in sizes from 1/2 to 2 in., the all-fluoropolymer gauge isolator has no wetted elastomers and uses a “double-pipe” design to completely eliminate the dead volume associated with traditional gauge isolators. The process liquid flows through a cylindrical Teflon membrane comprising the “inner pipe,” with the gauge fluid residing in the annular space between the Teflon membrane and the PVDF body. The gauge isolator comes in nine different styles of interchangeable end connections in PFA, PTFE, PVDF, PP, PVC and ECTFE (Halar).
