Any issues with the camper installations? I’m concerned now with installation on my four tanks.
For what it’s worth, my design includes 8266 module which is WiFi which allows me wireless connectivity to status panel I designed or to phone or tablet.
I may post the approach here if I decide the algae (or other material)film problem doesn’t prevent me from completing the installation.

I guess we'll have to look at using strain gauge sensors, weighing the contents! Most bathroom scales are using this technique effectively. Who ever thought that strain gauges would get so inexpensive over the years?
