There's this tank monitor as well.
I've been using it for 5 years, solar powered and no recurring fees. It's been working great and I also integrated it to my Home Assistant. Integration and setup was really easy and their support has been great. Their app is also filled with the data I actually need (consumption calculation and seemingly unlimited data history).
You can find these guys here: www . centriconnect . com and you can buy their product on Amazon.
$275. Ouch! Good to have another option and I guess I'd use it if I really needed to monitor a remote location, but at that price I'll just write myself a calendar reminder to trudge out and check the tanks once a week. These things don't need to do anything but read the position of a dial that's deigned to be read by a sensor. You'd think someone could design one at a reasonable price.
Sinope zigbee monitor is also not cheap, but it's been working fine for me.
Trudging is fine, but snow and a hill is involved for me.
The advantage of the one linked above is its cell connection in case the tank is beyond zigbee range. Not sure it can be directly linked with Hubitat though. Might require HA.
