Anybody knows what approximately should be the sensor resistance?
My sensor was never connected and I thought of building a circuit to get the level reading.
Connecting an ohmmeter to the exposed wire ends I get several hundreds of kilo-ohms and I suspect part of it is due to wires corrosion.
what i know, its only a full level indicator. It shown on the panel with the red led.
You can not measure any resistance unless there is no liquid contact.
liquid closes the circuit. No liquid no circuit. on of switch like. sorry bad english
the liquid opens or close the circuit
Thanks. If this is the case I will continue using my good old "level meter" - tapping along the sides of the tank and listening what sound it makes

I shine a little LED torch through the side of the tank - you can see a change as you move above and below the liquid level.
