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.
Liquid level controller circuit diagram.
The author investigated several approaches to the problem.
This post is about the three water pump motor water level controller wiring diagram with thermal overload protected relay magnetic contactor 4 pole mcb circuit breaker and water or liquid controller.
Liquid level controller circuit the figure givenin circuit diagram tab1 shows complete schematic diagram of the system.
Automatic water or liquid level controller wiring diagram.
In the below diagram is about the water level controller.
In a typical application where the device is employed for sensing low water levels in a tank a simple steel.
Connections the port p1 is connected with digital outputs d0 d7 of adc.
Here is a simple level switch circuit that switches on one relay and switches off another relay when the fluid level exceeds the set limit this circuit is a modification of the simple water level indicator.
The circuit described here lets you control a cellar drainage pump so that it turns on when a preset liquid level is reached and turns off again when a different preset level is reached.
You can run the motor manually and automatic using the switch.
In the diagram the over head tank and under ground tank connection shown with sensor.
