Abstract

An electrode assembly (23), comprising a casing (41), electrodes (31, 32, 33), a stopper (34) and a potting material. A housing (41) has a first end and a second end, and electrodes (31, 32, 33) extend from the first end of the housing (41) to the process fluid. A stopper (34) is arranged inside the housing around the electrodes (31, 32, 33). The potting material (48) fills the void between the first end of the housing (41) and the second end of the housing (41), such that the potting material (48) is subjected to pressure from the process fluid at the electrode head (32). Displacement of the electrodes (31, 32, 33) is limited under pressure.

Description

technical field [0001] The present invention relates generally to fluid handling, and in particular to fluxmeters for measuring process fluids. In particular, the present invention concerns electrode assemblies for fluxmeters subject to high process pressures. Background technique [0002] Flow sensors provide use across a broad range of fluid handling applications, including agriculture, environmental control, water and air distribution, food and beverage preparation, bulk fluid storage and delivery, chemical and pharmaceutical production, energy and hydrocarbon fuel preparation, and utilization Manufacturing processes for thermoplastics, adhesives, resins and other fluid materials. In each of these applications, the most suitable flow measurement technique depends not only on the properties of the process fluid itself, but also on the specific flow process to which it is applied. [0003] Standard flow measurement techniques include turbine flowmeters, which characterize...
