Can I just say Hallelujah! Newmar is done with KIB. As many of you know, I, as many others, have had issues with my black tank sensors reading properly from year 1. I've had new sensors, water pump relocated, new board, software updates, tons of recalibrations to no avail. This past visit to Newmar has taken care of my problem. Newmar unplugged the KIB pad on the tank and installed a a sensor by the gate valve that works by pressure (gravity). The higher the water level, the more pressure you have. It is working so far. No red lights, no showing 100% full when empty. It's the little things! Oh and the floater is still in the tank, so IF you do get a full tank reading when you think it's not full, you can pull the famous yellow wire and if it is still red, you know you are full. ?
 
Can you post a picture of the new sensor? Does it still send data to your kib display for tank readings?

Ah, good question. My display works and seems to be very accurate. Yay. The pad on side of tank is disconnected, but the floater still works. Dang, I didn't ask how the readings were getting to the display. I'll send a photo in the morning.
 
Just emptied my tank and it says 0%. Is this sad that this makes me so happy? ?

This device makes more sense than any other device I have seen!!!

Its a simple pressure switch. Failure is easy to fix, and accuracy is all but guaranteed. Amazing.
 
I'm more concerned about the floaters ?

For those wondering about the picture, this looks to be just ahead of the gate valve. I'm curious how it can really sense pressure differentials and know percentages especially between what goes in black vs. gray. I can understand a no/low pressure, i.e. an empty reading but above that I'm curious.

Take a look at this description of the process.

 
This is such an obvious design Improvement, I don't know why this hasn't been done before now.

Based on Newgle, it looks like Newmar started using the Kavlico pressure sensor in 2011 and moved it down to the next model each year and by 2015 all of the luxury models were using it. I’m guessing they did not introduce it to the Dutch Star on down models as a way to maintain the difference in the various models. Perhaps also due to the tie-in with Silverleaf.

Given that Newmar has retrofitted Renee’s coach with a pressure sensor, I’m curious if this is now standard on current year Dutch Star and perhaps other models.
