For us the main concern with tank accuracy is the black tank sensor, the grey is easily disposed of so we are less concerned with accuracy. Our coach has the standard control panel that gives the false readings. Our toilet however is a Tecma macerator toilet, the toilet comes with additional sensors that mount outside the tank, The pushbutton flush on the wall starts Green, then goes Amber, then Red, These readings are accurate and at least our Black tank volume is clear to us. The bottom line, you could change the toilet, that will solve half the problem, G
