- This simple tool is when the water level rises and touches the probes, the A.C signal will get through, causing the alarm oscillator to switch on and sound the alarm.
- This kind of circuit for detecting the level of water in a tank is that a direct current (D.C) flow trough the sensor electrodes.
- The alarm oscillator will remain disable when signal is not received at at the probe and there are no D.C
