FWIW, and not sure if have brought this up in past, etc., and am pretty sure most of you know about/realise this, but, if you actually make use of pouring sensors/liquid level indicators, it's worth remembering that often enough when they die/stop working, it's just that the battery has run dry/died, and, I recently went and got replacement batteries for 2 of them at local hardware store, just by taking the batteries there, and they cost like R7.50 each, whereas if had wanted to replace sensor units themselves, they would have been like over R150 each at like council shop, etc., but anyway.
