I like to develop a water level monitoring for my Cistern tank. Monitor Empty level, low level, mid level, high level. One of my booster pump broke because it is running even there is no water in the cistern tank.

One of my option is some previous answer related to water level monitoring

Is there a risk of 220v ac flowing in the water how to avoid it? I don't know any micro controller or programming of it so I choice hard wiring and indicator light.


Second option is to use float less relay ANLY a61F-G3

But how to have indicator light in lower limit (E4) and high limit (E1) separately. Because the indicator light option is available only for lower (E3) and high (E2). How to have a water level monitoring regardless if you have a motor or not the simplest way
