Yn. Mikhailovskii et al., Monitoring of the corrosion state of underground pipelines with corroding resistors-transducers, PROT MET R, 36(6), 2000, pp. 583-587
Two types of resistors-transducers were designed to measure the underground
corrosion rate of steel with an accuracy of +/-10%. The transducers were f
ield tested at the operated Mostransgaz and Tyumentransgaz gas mains.
