Fully Automatic Water Level Controller for Submersible Pumps

Smart Tank Automation with Dry Run & Overflow Protection

Managing a submersible pump manually can lead to motor damage, water overflow, electricity wastage, and constant monitoring stress. This Fully Automatic Water Level Controller is engineered to eliminate those risks through intelligent water detection and automated pump control.

Designed specifically for submersible pump systems, this controller ensures your water tank fills safely and efficiently — without human intervention.

Intelligent Working Mechanism

The system continuously monitors two critical conditions:

1. Water availability in the source

2. Water level inside the storage tank

Step-by-Step Operation:

• When water is detected at the source, the controller initiates a controlled 5-second delay.

• After the delay, the pump is activated through a high-performance relay.

• The pump continues running only when:

  • Water supply is available

  • The storage tank has not reached full level

The moment either condition changes, the controller instantly shuts off the pump.

Dual Protection Safety System

✔ Dry Run Protection

If water supply stops unexpectedly, the controller immediately switches off the submersible pump to prevent motor overheating and coil damage.

✔ Overflow Prevention

A dedicated tank level sensor detects when the tank reaches full capacity and automatically stops the pump to prevent water wastage.

Core Functional Advantages

• Automatic detection of incoming water supply

• Real-time tank level monitoring

• Built-in 5-second safety delay before pump activation

• Intelligent relay-based pump control

• Automatic shutdown in two safety scenarios

• Eliminates manual switching errors

• Increases pump lifespan

• Reduces electricity consumption

• Ensures efficient water management

Designed for Reliability & Convenience

This controller removes the need for continuous supervision. Whether installed in residential buildings, apartments, or commercial properties, it guarantees:

• Consistent tank filling

• Protection against dry running

• Prevention of overflow

• Hassle-free, fully automatic operation

Ideal For

• Homes using submersible borewell pumps

• Apartment water systems

• Commercial tank installations

• Locations with irregular water supply

Why This Controller Matters

Submersible pumps are expensive and vulnerable to dry running damage. Water overflow leads to unnecessary water and power loss. This automatic controller addresses both problems with precision and reliability — ensuring your water system operates safely every time water is available.
