Device for determination of fluid parameters and fluid composition control based on on-line measurement of such fluid parameters using twin ultrasonic transducer and reflector arrays for accurate measurement of fluid parameters

摘要

Device comprises two reflectors for use with ultrasonic transducers. The reflectors are placed in the measurement chamber at different distances from the transducers. Switching on or off of fluid movement through the measurement chamber is controlled using a valve connected to atmosphere with operation condition dependent. The measurement process depends on whether the reflector surfaces are covered by fluid or not. According to measurements of flow times and ultrasonic echo impulse amplitudes the following physical parameters are determined: density, ultrasound velocity, compressibility and viscosity. Similarly any changes in the parameters can be determined.
