Troubleshooting your fuel level sender

I've been taking readings all week from the right side sender in order to get the right sender in my new lpg tank.

The readings below.

Fuel gauge reading
Full 47ohm
3/4 210ohm
1/2 243ohm
1/4 326ohm
Empty 326ohm

So I'm guessing this is not gonna be accurate if rx8 somehow averages out from two senders?
I noticed the reading of 326 never changed between below half and empty !!? Drove me crazy
Maybe the two senders merge their wires parallel and cld be measured at that point?
