Let say an analog water level sensor with voltage output range between 0-5Vac / 0-500ft installed with cable length of 300ft. The sensor outputs a voltage of 2.5V corresponding to an equivalent level of 250ft.
How can I negate the voltage drop due to cable length, cable size, temperature etc. to have an accurate reading.
Are there any circuit to solve this problems?
Or would the voltage drop (in any cable length) be neglible not to affect much on the voltage output?
Thanks!
