Abstract
An amperometric sensor assembly includes an amperometric sensor and a bubble shedding clip. The amperometric sensor has a sensor membrane that is configured to be exposed to a process fluid. The amperometric sensor also has an electrical characteristic that changes based on exposure to an electroactive substance. The bubble shedding clip is coupled to the amperometric sensor and is configured to inhibit the presence of bubbles on the sensor membrane when the sensor membrane is exposed to the process fluid. A water panel including the amperometric sensor assembly is also provided along with a method of installing a bubble shedding clip on an amperometric sensor.
Claims13
An amperometric sensor assembly comprising:
- an amperometric sensor having a sensor membrane configured to be exposed to a process fluid, the amperometric sensor having an electrical characteristic that changes based on exposure to an electroactive substance, the amperometric sensor having a cylindrical probe body and a membrane retainer coupled to the cylindrical probe body, the membrane retainer being configured to position the sensor membrane proximate a sensing element of the amperometric sensor;
- a bubble shedding clip coupled to the amperometric sensor, the bubble shedding clip being configured to inhibit the presence of bubbles on the sensor membrane when the sensor membrane is exposed to the process fluid;
- and
- wherein the bubble shedding clip is clipped into a gap between the membrane retainer and the cylindrical probe body.
A water panel comprising:
- a low flow controller having an inlet configured to receive a flow of process fluid, the low flow controller being configured to provide a controlled flow of the process fluid to an outlet;
- a low flow cell having an inlet operably coupled to the outlet of the low flow controller, the inlet of the low flow cell being disposed at a bottom of the low flow cell;
- an amperometric sensor assembly disposed within the low flow cell, the amperometric sensor assembly including:
- an amperometric sensor having a sensor membrane configured to be exposed to the process fluid, the amperometric sensor having an electrical characteristic that changes based on exposure to an electroactive substance, wherein the amperometric sensor includes a cylindrical probe body and a membrane retainer coupled to the cylindrical probe body, the membrane retainer being configured to position the sensor membrane proximate a sensing element of the amperometric sensor, and
- a bubble shedding clip coupled to the amperometric sensor, the bubble shedding clip being disposed between the inlet of the low flow cell and the sensor membrane,
- wherein the bubble shedding clip is clipped into a gap between the membrane retainer and the cylindrical probe body.
