This is the Simple Water-level indicator Circuit Diagram. n this a
warning device WD1 is in series with SCR1. When the liquid level causes a
conductive path between the probes, the SCR conducts sounding WD1. The
warning device may be a Sonalert (TM), a lamp or a buzzer.D1 acts as a
transient suppressor. Press SI to reset the circuit.
