The iSeries seems like a good product but for that price, you might as well go for a Victron Cerbo GX <https://amzn.to/3u8gg4u>, it will read 4 resistive tank senders, 4 temperature sensors, 4 digital inputs (bilge alarms, open hatches, engine data, etc.), can integrate with all CAN bus systems including chargers, inverters, battery monitors, and it can communicate with NMEA2000 devices. All data is recorded and uploaded to your Victron VRM account (free) and can be accessed anywhere in the world (with WiFi connection). I use mine to monitor all the water tanks and the holding tank. It has a programmable relay output and I have mine set to disable the electric head when the holding tank is full so that it can't be overfilled. The possibilities are endless.
