Electrochemical corrosion potential probe assembly

摘要

An electrochemical corrosion potential (ECP) probe assembly for monitoring ECP in a high velocity reactor line includes an airfoil shaped ECP cover that improves the streamlines over and around an ECP sensor. The airfoil shaped cover includes flow holes drilled normal to the surface of the ECP cover. As such, the direction of flow of reactor water into the ECP probe assembly is altered to reduce the flow rate internal to the ECP cover sufficiently to prevent damage to the ECP probes. To facilitate use as a retrofit component, the ECP cover may have an elliptical section that is contiguous to a circular section that conforms to the geometry of existing probe wells and probe sub-assemblies.

1. An electrochemical corrosion potential (ECP) probe assembly, comprising:
at least one ECP probe; and a probe cover enclosing the at least one ECP probe, comprising:
an elliptical cylinder that extends around the at least one ECP probe, the cylinder having a leading edge seam and a trailing edge seam;a top panel that encloses an end of the elliptical cylinder; anda plurality of leading flow holes formed on both sides of the leading edge seam and a plurality of trailing flow holes formed on both sides of the trailing edge seam.
