YT2095...yes thats how i have measured the water level. What i have done is started with a set amount of water (say 200ml) then added cubes of metal to this water (i have recorded the area of each cube), Then i have measured the difference in resistance each time i put a cube in. hope this makes more sense.

I have conducted a experiment to measure water displacement using a variable resistor. However i am now stuck, is there a equation to convert resistance into water displacement. i also have the water level im ml. any help would be much appreciated, thanks alot, hwk

rite thanks alot, tried google, no good results come up but i'll try those other two sites.

ok thanks alot, are there any good websites with more information on? as i cant seem to find any:mad:

I am reserching Scanning Tunneling Electron Microscopes, what are pro's and con's of them? any help would be appreciated, thanks for any help.
