Both tanks contain enough biological material to connect the sensors creating the inaccurate readings.
Rv waste tank sensors.
Each system provides tank level information using a percentage of full readout.
The inventor of the horst miracle probes now has an even better invention.
The sensors are placed at equal intervals in the black water tank like 1 3 2 3 and full.

The waste tanks are more prone to sensor issues simply because of the nature of the materials contained than fresh water tanks so we will focus on those.
The sensors are external and will not affect your readings by sewage buildup.
Why your gray tank sensors aren t working correctly.
