A device for measuring the characteristics of a flow within a pipe, the flow having a flow direction and the device comprising: a plug having a nose at a forward end of the plug facing the oncoming flow, a body attached to the nose and a tail attached to the body at a rearward end of the plug; two or more strut assemblies, each strut assembly comprising: a forward strut having a first end and a second end, said first end of said forward strut being fixably attached to said plug proximate said forward end; a rearward strut spaced apart from the forward strut and having a first end and a second end, said first end of said rearward strut being fixably attached to said plug proximate said rearward end; a skid having an inner surface, said skid being fixably attached to said second end of said forward strut and said second end of said rearward strut such that said inner surface faces said plug; the device being characterized by: said plug having at least one portion having a constant diameter that is smaller than the adjacent forward end facing and rearward end facing portions of said plug, forming at least one venturi; and an electrical impedance spectroscopy sensor located on said inner surface for measuring said characteristics of said flow. a plug having a nose at a forward end of the plug facing the oncoming flow, a body attached to the nose and a tail attached to the body at a rearward end of the plug; two or more strut assemblies, each strut assembly comprising: a forward strut having a first end and a second end, said first end of said forward strut being fixably attached to said plug proximate said forward end; a rearward strut spaced apart from the forward strut and having a first end and a second end, said first end of said rearward strut being fixably attached to said plug proximate said rearward end; a skid having an inner surface, said skid being fixably attached to said second end of said forward strut and said second end of said rearward strut such that said inner surface faces said plug; a forward strut having a first end and a second end, said first end of said forward strut being fixably attached to said plug proximate said forward end; a rearward strut spaced apart from the forward strut and having a first end and a second end, said first end of said rearward strut being fixably attached to said plug proximate said rearward end; a skid having an inner surface, said skid being fixably attached to said second end of said forward strut and said second end of said rearward strut such that said inner surface faces said plug; the device being characterized by: said plug having at least one portion having a constant diameter that is smaller than the adjacent forward end facing and rearward end facing portions of said plug, forming at least one venturi; and an electrical impedance spectroscopy sensor located on said inner surface for measuring said characteristics of said flow. said plug having at least one portion having a constant diameter that is smaller than the adjacent forward end facing and rearward end facing portions of said plug, forming at least one venturi; and an electrical impedance spectroscopy sensor located on said inner surface for measuring said characteristics of said flow.
