Use of ultrasonic standing wave method to measure the viscosity of oil through a metallic component. Continuous repeated chirp raw data for measurements of cannon standard oils

Files are uploaded in CSV format Each contains 3-4 columns of amplitude data taken using the CRC method in the time domain, this is raw data. To plot amplitude against time use dt=32ns. (or time=[32:32:10000000]*1E-9;) _R or _r files refer to reference files : i.e. Data captured from a solid- matching layer- air interface. _M or _m file refer to measurement files: i.e. Data captured from a solid-matching layer - liquid (oil stated in title) interface.
