| Remote Corrosion Monitoring
System for Gas Distribution System: An automated
corrosion monitoring system used by Centra Gas Manitoba (Canada) in its distribution
system has been described in the Pipeline & Gas Industry publication, October 2001
edition.
System Features:
- Measurement of corrosion protection potentials and end-pressure.
- Communication with remote monitoring units via telephone line (cell phone
compatibility has not been ruled out for the future).
- Increased measurement frequency over manual readings.
- Focus on cost effectiveness and simplicity.
- Measurement accuracy at least similar to manual readings.
- Remote monitoring units read and store data, call in to central host
computer at a prescribed time to upload information.
- Customized system developed.
- Further improvements, refinements expected with time.
Benefits:
- Trend identification in corrosion protection levels.
- Identification and correction of problems such as "shorts", depleted anodes in
shorter time frames.
- Cost reduction in readings.
- Early warning of future upgrade / maintenance requirements.
- Improved scheduling, reduction in unplanned work and system outages.
- Anticipated overall improved system safety and integrity in the longer term, as more
data and information is generated.
