A microwave-based emulsion treating method and system comprising a microwave energy source, a microwave applicator for treating an emulsion, a separator vessel for receiving and separating microwave-treated emulsion, an oil-water analyzer for determining water content of the emulsion feed, and water supply means including control means responsive to the analyzer for adding a controlled amount of water to the emulsion feed going to the applicator. The added water may be recirculated from the separator.

Microwave emulsion treater with controlled feed water content

A dual element strain gauge is placed near a welded or otherwise constrained joint on a structural member so as to provide a constraint factor. The location for the strain gauge must be selected to provide constraint factor that is preferably near either maximum or minimum value. The strain gauge is monitored to detect a change in the initial constraint factor, which indicates failure has begun or is imminent.
