Automatic water level controller circuit leaf switches s1 and s2 used in tape recorders are fixed at the top of the sensor units such that when the floats are lifted the attached 5mm dia.
Here is a simple level switch circuit that switches on one relay and switches off another relay when the fluid level exceeds the set limitthis circuit is a modification of the simple water level indicator previously postedwhen the water level touches the probes positive supply is connected to the base of q1 through fluidthis makes transistor. The new circuit diagram for the logic side of the circuit is as follows. This is a circuit for water level controller is based on transistors and relays. This is a typical relay based control system that is used to control liquid level in the tank. The lm1830 fluid level detector circuit is a device intended to signal the presence or absence of aqueous solutions featuring low external parts count wide supply operating range internally regulated supply and ac or dc output. The arduino mega is connected to a prototype circuit board that interfaces with the screen buttons and potentiometers.
This page provides a reference design for an arduino based circuit showing the simplest device embodiment including pressure sensing. Approx aluminium rods push the moving contacts p1 and p2 of leaf switches s1 and s2 from normally closed nc position to normally open no position. Electromechanical relay control systems were one of the first types of control systems used in the process control industry to perform onoff control.
