of measuring the corrosivity of proces stream conditions by the use
of probes which are inserted in the process stream and which are continuously
exposed to the process stream conditions. Corrosion monitoring probes
can be mechanical, electrical, or electromechanical devices.
FOR CORROSION MONITORING:
providing early warnings
studying the correlation of changes in process parameters to its
diagnosing particular corrosion problem
evaluating the effectiveness of corrosion control/prevention method.
providing management information relating to the maintanence requirements
and ongoing condition of plant.
OF CORROSION MONITORING TECHNIQUES:
risks are very high
process upsets can cause high corrosivity
corrosion inhibitors are in use
process feedstock is changes
the evaluation of corrosion behaviour of various alloys.
product contamination due to corrosion is a vital concern.

Electrical resistance technique is one of the methods of OnLine Monitoring
of the corrosion phenomena. It measures the rate of corrosion and
the extent of metal loss for any metallic equipment or structure.
The E/R Monitoring system consists of a sensitive probe element (Composition
of the element being similar to the process system of interest) connected
to an electronic instrument. The system measures the change in the
electrical resistance of the probe element as the metal loss occurs.
The rate of change is directly proportional to the corrosion rate.

are applicable to all working environments gases, liquids, solids,
measurement of rate of corrosion.
quickly to corrosion upsets.
Polarization resistance technique is one of the methods of online
monitoring of the corrosion phenomena.
of linear polarization resistance may be briefly stated as follows:
of an alloy/metal electrode in an electrolytically conducting medium
of sufficient oxidizing power will lead to corrosion of the electrodes
by electrochemical mechanism. The rate of corrosion is proportional
to the gradient of the corrosion potential vs current curve.
monitoring system consists of sensitive probe element (composition
of the element being similar to the processing system of interest)
connected to an electronic instrument.
a low amplitude voltage is applied across the electrodes and the resulting
current is measured which is correlated to the corrosion rate.
terms, corrosion rate of a probe is inversely proportional to polarization
