Good find although more componets would be needed.
Its basically a Analog level sensor to NMEA 2000 converter so you would need an analog level sensor.

To calibrate it you would most likely need one of the Lowrance gauges or MFD that is describe in the calibration procedures in the manual. NMEA calibration PGNs are I believe all proprietary so while the level signal could be displayed on any appropriate NMEA 2000 display to calibrate that signal you would need Lowrance device.

Its similar to the Maretron TLA100 although limited to a 5 point calibration while the Maretron allows for a 16 point calibration. Marathon TLA100 is significantly more expensive for the device but when you add the analog sensor and the NMEA 2000 display the cost benefit of a Lowrance based solution may be reduced.

Another Maretron solution is the TLM100 which includes an ultrasonic level gauge but both the Maretron solutions certainly exceed your $150 price point.
