It sure will Rod and welcome back. The SeeLeveL RV Holding Tank Monitor item # SE34VR will indeed function to monitor the battery and water levels on your fresh, gray, and black tanks without connecting the propane sensor.
The propane monitoring feature obviously won't work so you'll want to cap off the propane wire when installing the system so you don't have to worry about the monitor shorting out.
The SeeLeveL RV Holding Tank Monitor item # SE34VR is just the monitor. For the monitor and water tank sensors you'll need the SeeLeveL RV Holding Tank Monitoring System item # SE59VR.

Rod: Jarred asked me to provide you with my experience in installing and using the SeeLevel System in my Newmar Class A (2009). My original tank level system never worked and the company that made it was bought by another company. I called the new company and got a person that was employed at the original company and had moved to the new company. He was extremely helpful in telling me that I could not get parts to repair or upgrade the system I had. He recommended that I try SeeLevel. I did my homework and contacted SeeLevel directly in Canada and got all my questions answered and even was passed to the SeeLevel operation only 50 miles from me near Fort Worth, Texas. A person there was extremely helpful in not only understanding what the system would do but helping me with install instructions. I installed the system myself. My challenge was using the existing wires of the old system. My tanks are on the other end (and side) of my coach and the monitor location was over the entry door. It would have been almost impossible to run new wire to the tanks from the monitor so I began to study how to use the existing wires instead. I was able to use what documentation I had on the old system and the SeeLevel system to figure out how to hook up all the tanks (black, grey, fresh, LP, battery). It went fairly easily. I really like the SeeLevel system and have had no problem trimming detectors to the right size for the tanks I have. The trimming did not affect the 1 to 100 percent indication on the monitor. The system is pretty smart in that regard. If you get in a bind call SeeLevel. They are extremely helpful. The system works even if you don't hook up the LP tank for sure. I found using WEGO electric connectors made the installation far easier because it would allow you to easy swap wires if you happened to hook up ground and signal wires incorrectly the first time. I got lucky and did not have that problem but being able to quickly connect and disconnect wiring is a nice thing to have. I did some testing to measure exactly how much water I put in each tank and checked that against what the SeeLevel System read-out said. It was pretty close. Close enough for me anyway. I hope this helps you. Jim

Thanks, I have a Forest River Wolf Pack and the existing tank monitor died. Another question: I have 8” tall tanks so I’ll need to cut down the 12” sensors. Does the resolution accuracy go down by cutting off 1/3 of the sensor? I noticed the sections are smaller on the 12” (and even more so on the 9”) compared to the 16” sensors. Rod
