pls help me to build water level meter.the one i made uses 5 probes for empty,quarter,half and full.Now a want a better design.can i use uvison and simulate something. what
Can we have more insight into the dimensions of the water vessel to be measured?
Do you want to go with a simple expansion to 8 probes, or would a float and potentiometer be appropriate?
Perhaps ultrasonic rangefinder to detect depth to water?
Probe that changes capacitence as the water level increases?
At the extreme, a lovely woman with a tape measure. Pleasant to look at and voice output.
Many ways to approach this, but we need to know more details of the application first.
Unfortunately, that seems unlikely - the OP seems to have lost interest.

"Unfortunately, that seems unlikely - the OP seems to have lost interest."
Google does not show any cross-posts, but most forums don't get scanned by Google. Not impossible that the OP did get a better answer - or a full solution - from some other site.
Which would tend to make him lose interest in his other thread(s)...
hey...who has any idea on how can i build a water level sensor using a one probe only....meaning the output or reading will be linearly..has anyone.???
I guess you did not read this thread.
There are a number of suggested designs in this thread for measuring the water level with a single sensor.

"The devices rely for their operation on the sensitivity of the PTC element's tip to variations in ambient thermal conditions. The transition from liquid to air and vice versa causes the rate of thermal loss to change very quickly as does the resistance of the PTC element. This allows the device to record very simply and exactly whenever a liquid goes above or below a certain level."
