Smart Water Tank Management — Simplified with Qtanq

---

Qtanq operates through a smart, fully automated process designed to make water management simple and reliable. It begins with sensing, where advanced ultrasonic or float sensors continuously monitor the water level with high accuracy. Once detected, the system moves into control, automatically switching the water pump ON or OFF depending on the set thresholds — ensuring optimal levels at all times. Next comes alert, where users receive real-time notifications or updates through a control panel or connected interface, keeping them informed without any manual checking. Finally, Qtanq helps optimize water usage by preventing dry runs, avoiding overflow, and reducing unnecessary energy consumption — making it a complete, intelligent solution for efficient water management.

Qtanq is built with a range of intelligent features that make water management effortless and efficient. Its smart sensing technology ensures accurate, real-time water level detection, while automatic motor control takes care of switching pumps ON or OFF without human intervention. The system supports multi-tank management, making it ideal for setups with both overhead and underground tanks. With mobile and panel alerts, users can stay informed about tank levels and pump status anytime, anywhere. Qtanq also allows customizable thresholds, letting users set water level limits and notifications according to their specific requirements. Designed for energy efficiency, it prevents pump overuse and protects against dry runs, reducing maintenance costs and power consumption. Built to withstand diverse environments, its durable and weatherproof construction ensures long-lasting, reliable performance in any setting.

Qtanq stands out from traditional water management systems through a series of intelligent improvements designed to make every drop count. 

1. It eliminates the need for manual monitoring by automating the entire process — from detecting water levels to controlling pumps.
2. It introduces smart cut-offs that prevent overflows, saving both water and energy. 
3. By incorporating dry run protection, Qtanq safeguards your motor from damage and extends its lifespan. 
4. It goes beyond basic functionality by providing real-time insights into water usage and tank levels, helping users make informed, data-driven decisions. In short, Qtanq replaces guesswork with precision, ensuring efficient, automated, and worry-free water management. 

Qtanq is designed to adapt seamlessly across a wide range of environments, making it a versatile solution for efficient water management.

Model: QTanQ Overhead Tank Automation Unit
Application: Automatic Water Level Management – Overhead Tank Only
Mounting: Supplied within a compact powder-coated CRCA enclosure

Scope of Supply:

• One fully wired automatic control panel with embedded logic controller
• Two magnetic float switches for overhead tank (Low & High level detection)
• Industrial-grade contactor and relay set for pump switching
• Built-in over-voltage and under-voltage protection circuit
• Manual override switch for on-site testing or emergency operation
• Powder-coated CRCA enclosure with structured internal wiring and terminal blocks

System Function:

QTanQ-OH is an automatic pump control system designed to operate solely based on the water level inside the overhead tank. The motor switches ON when the low-level float is activated and switches OFF once the high-level float is reached. The system is equipped with electrical protections to prevent motor damage from unsafe voltage conditions.

This model does not include sump monitoring or dry-run protection. Suitable for setups where only overhead tank automation is required.

Technical Specifications:

• Operating Voltage: 230V / 415V AC
• Control Voltage: 12V / 24V DC
• Switching Capacity: As per pump HP rating (to be specified)
• Float Switch Type: Magnetic / Mechanical
• Switchgear: Schneider / Siemens / ABB or equivalent
• Enclosure: Powder-coated CRCA cabinet with internal cable dressing and termination layout

Model: QTanQ Dual-Tank Water Automation Unit
Application: Automatic Water Level Management – Overhead Tank + Sump Inlet Regulation
Mounting: Supplied within a powder-coated CRCA enclosure

Scope of Supply:

• One fully wired automatic control panel with embedded logic controller
• Two magnetic float switches for overhead tank (Low & High level detection)
• One float switch for sump level detection
• One solenoid valve for automated inlet regulation from PWD line
• One manual bypass line for solenoid valve servicing or failure
• Industrial-grade contactors and relays for motor control
• Integrated over-voltage and under-voltage protection module
• Manual override switch for pump testing or emergency activation
• Powder-coated CRCA enclosure with internal cable management and termination blocks

System Function:

QTanQ-DX is an integrated water automation system that controls both the filling of the overhead tank and the regulation of water inflow into the sump, providing complete automation for dual-point water management.

Overhead Tank Automation (QTanQ-OH Logic):

The system automatically starts the pump when the overhead tank reaches the low-level float and stops it once the high-level float is activated, preventing both overflow and dry tanks.

Sump Inlet Regulation:

A float switch inside the sump monitors its water level. When the sump reaches full capacity, the connected solenoid valve automatically shuts off the PWD water inlet to avoid overflow.
A manual bypass line is included, allowing continued operation in case of solenoid valve malfunction or maintenance.

Technical Specifications:

• Operating Voltage: 230V / 415V AC
• Control Voltage: 12V / 24V DC

System Function:

QTanQ-UG is a fully automatic underground sump management system designed to control the operation of a single pump based on sump water levels. The system continuously monitors the water level using two magnetic float switches:

• When the sump level falls below the Low-Level float, the system automatically switches OFF the pump to protect it from running dry.
• When the sump level rises to the High-Level float, the system automatically switches ON the pump to resume operation.

This ensures consistent automation of the water supply process, eliminating manual intervention while extending pump life through integrated protective features. The control logic prevents short-cycling and provides clear visual feedback through panel indicators.

Technical Specifications:

• Operating Voltage: 230V / 415V AC
• Control Voltage: 12V / 24V DC
• Float Switch Type: Magnetic / Mechanical
• Protection Features: Dry-Run, Overload, Over/Under Voltage
