HIGH PRESSURE MAGNETIC FLOWMETER WITH STRESS RESISTANT ELECTRODE ASSEMBLY

Title:

HIGH PRESSURE MAGNETIC FLOWMETER WITH STRESS RESISTANT ELECTRODE ASSEMBLY

Document Type and Number:

WIPO Patent Application WO/2010/014729

Kind Code:

A3

Abstract:

An electrode assembly [23] comprises a housing [41], an electrode [31, 32, 33], a retainer [34] and a potting material. The housing [41] has a first end and a second end, with the electrode electrode [31, 32, 33] extending from the first end of the housing [41] to a process flow. The retainer [34] is positioned about the electrode [31, 32, 33], inside the housing. The potting material [48] fills voids between the first end of the housing [41] and the second end of the housing [41], such that the potting material [48] limits displacement [31, 32, 33] of the electrode when the electrode head [32] is subject to pressure from the process flow.
