automatic water pump controller, which maintains water in a tank between two levels.?

can it b done by usin 1 single nand gate? as the logic will be.. output is 0 when both the levels are crossed ( ie both levels are at 1 state) . how can the circuit be practically realised?? 1 state corresponds to sensor reading as 1 when the levels are crossed. and also what kind of sensors are best suited for point level sensing, and also economic.

floats are the cheapest, with the float controlling a switch.

You need two floats, or one float with two different switches. You may need a latch of some sort, or a latching relay.

lower switch turns pump on, upper one turns pump off.
