I'm designing a water level controller. It has to be designed using conventional method of (probes in water). Actually the distance between the tank and base unit is almost 1 Km . wires have been layed out. I want to know what method should i take to do these level sensings (10 levels) at such a long distance. i mean should i use some special amplifying stage filters etc. One thing more I think a low amplitude ac signal should be transimitted in water to prevent salt formation. what should be the frequency of this signal. Do i need a amplifier in base unit for transmiting a strong signal for this distance range. One last thing i cannot design any unit at the tank end. only one base unit.
Thanks.
