Relationship between fuel tank floater and resistance in ohms
Hello-
For my EG fuel tank floater, it measures 2-5 ohms when full and 150-155 ohms when empty.
Does anyone know offhand if the relationship between fuel level and resistance is linear?
In other words, is it safe to assume since 2-5 is full and 150-155 is empty, then halfway must be ~75 ohms?
Thanks!

Re: Relationship between fuel tank floater and resistance in ohms (B18EG6)
the manual says:
2-5 ohms full
25.5-39.5 half full
105-110 empty
so,it doesn't appear to be linear.

Thanks for the reply.
Are you consulting the Helms manual for a 92-95 civic? Or did you look at a Helms for a teg?
The only strictly civic manual I have is haynes, and those are the only numbers it gave me (i.e. full and empty resistence)

that is from an Interga manual-it's all i have here.i can confirm that in a Civic manual today at the shop.

Thats also what my 92-95 Civic service manual says too.

I'd find it hard to believe that the sweep of the fuel tank level sensor isn't linear...it should just be a potentiometer.
But since the fuel tank is shaped the way that it is, its volume doesn't change in a linear way.
What are you trying to do? Is there a problem with the level sender?

Awesome, thanks. My teg Helms gives those values also, u consulted a civic Helms in confirming those values? Does that mean the tanks are shaped similiarly?

Yeh I was figuring its a pot also... There is no problem with the level sender, I am redoing my gauge cluster and I was looking at aftermarket senders and what their values correspond to. I was going to use the stock sender with aftermarket gauges in the cluster. To avoid buying a different I was going to utilize the stock one.
So long as the resistence values match up to the correct fills, it would work correct?
