8.2.2 The second usage: Metal container
Containers made of metal or other conductive materials; such as stainless steel iron, copper, aluminum alloy or materials with electroplated metal
layer on the surface. Because the capacitive sensor is sensitive to all conductive objects, such containers cannot be directly glued on the outside of the
container. Therefore, for containers of this type of material, it is needed to drill holes on the container, and the installation method is as follows.
Install method:
1. Prepare 2 rubber plugs and the needed tools for drilling holes.
2. Open one hole in the high position and one in low position, the hole diameter have to match the size of the rubber plug.
3. Put the rubber plug into the holes and check if there is water leakage. Add glue to seal the holes if necessary.
4. Glue the sensor on the rubber plug with glue and fix it with a support. Make sure the glue has solidified before removing the support. Example
of the installation method of the sensor with the metallic container is as follow Picture 2.
