Abstract
A dialysis system includes a dialyzer; a blood pump coupled operably to a dialyzer; a dialysate inlet pump couple operably to a dialysate inlet of the dialyzer; a dialysate outlet pump coupled operably to a dialysate outlet of the dialyzer; a first non-invasive fluid velocity sensor positioned to sensor of inlet flowrate of dialysate pumped to the dialysate inlet by the dialysate inlet pump; and a second non-invasive fluid velocity sensor positioned to sense an outlet flowrate of dialysate pumped from the dialysate outlet by the dialysate outlet pump.
