  • Fluid ingress?
  • Over-temperature?
  • Collision with military objects?

Check your grounding straps from pipe-to flow tube-to pipe.

This link might help: http://www.omega.com/toc_asp/frameset.html?book=Green&file=MAG_FLOW_REF

The last page explains the why of grounding. You should look at the book you got with your magmeter for the how.

Typically there should be a grounding strap from the flange of the inlet pipe, to the body of the flowmeter, to the flange of the outlet pipe, then back to a good ground. If your electronics are remote (vs. integral mount on flow tube), then it should be grounded with the tube as well.
