Development and calibration of the NWRI frazil instrument / by Gee Tsang and Manuel Pedrosa.: En13-5/83-16E-PDF
"After 10 years of development, a frazil instrument capable of measuring the point concentration of frazil in flowing water has been produced and calibrated. The instrument is based on the theoretical principle that when ice is formed, impurities are rejected, frazil therefore may be considered as electrically non-conductive and its concentration in water can be measured by comparing the resistance of a sample of frazil-laden water with that of a sample of frazil-freewater. The instrument was calibrated in the laboratory. The calibration testing showed that the instrument performed satisfactorily. Because the frazil crystals are not isotropic, a calibration factor F greater than unity is involved. The division of the measured concentration by F gives the true concentration of frazil in water. F is a function of the flow velocity and turbulence and can be obtained through calibration"--Abstract, p. i.
