System of complex corrosion monitoring of apparatuses and pipelines of oil production and oil refining objects.
Main>Products >Structural Health Monitoring systems >Integrated Corrosion Monitoring Systems

Automated systems of corrosion monitoring (CM) comply with the general concept of construction of TDM systems for control of hazardous production facilities with the purpose of their operation in the current technical condition and serve for regulation of corrosion behavior speed and optimization of chemical agents supply applied for protection of the instrumentation from internal corrosion.


Optimization of chemical agents supply for protection of the instrumentation from internal corrosion
Timely reaction to change of corrosion rate
Accumulation of data for the subsequent analysis and long-term forecasting of the instrumentation corrosive wear.
Automation of actions for protection of instrumentation against internal corrosion and lowering of the human factor function on estimation of the results of corrosion monitoring.


Automated systems of CM based on of Lel-M /A-Line 32D (DDM-M)/ functionally consist of three basic parts: the measuring, computing and executive ones.
The measuring part, as a rule, incorporates corrosion sensors, pH sensors, patterns, flowmeters and AE transducers.
The computing part is implemented in the central computer station.
The executive part consists of automatic dosing pumps controllers, pumps and chemical agent supply jets.

1. Corrosion sensors are primary transducers intended for measurement of corrosion rate through the method of electric resistance (ER) or the method of linear polarization resistance (LPR);
2. Transmitters are secondary converters connected to ER or LPR corrosion sensors, serve for measurement of corrosion sensor readings and their further transfer to standard interfaces in the analog or digital form;
3. pH measurement complexes are devices intended for technological process inspection and finding solutions to the problems of measurement and command of the executive instrumentation;
4. pH sensors are devices measuring pH level in aqueous phase (including in corrosive nature solutions);
5. Dosing pump automatic controllers (DPAC) is an electronic control unit of the dosing pump allowing control of corrosion protection agents supply;
6. Dosing pumps are electric pumps providing corrosion protection agents supply;
7. Flowmeters are devices intended for measurement of the corrosion protection agents consumption and allowing to supervise the result of DPAC control action.


  • Opportunity of forecasting of еру current corrosion condition of the object under control.
  • Measurement of the corrosion rate and on-line display of the received results.
  • Noninuform corrosion data acquisition
  • Characterization of current corrosion processes and their statistical evaluations.
  • Full-function command of DPAC operation modes and the dose level of chemical agents.
  • Integration with control stations for increase in efficiency of reaction in critical situations.
  • Usability.
  • High reliability and long-term service.
