Water scarcity and wastage are growing global concerns. In many regions, inefficient water management leads to overuse, pump failures, leakages, and unpredictable water supply. With increasing urbanization and industrial demand, traditional manual water systems can no longer keep up. Smart water management solutions that combine real-time monitoring, automation, and data-driven decision-making are now essential to optimize water use, reduce operational costs, and ensure sustainability.
IoT-enabled devices have emerged to address these challenges, including water level indicators, valve controllers, borewell schedulers, automatic TDS monitors, smart irrigation systems, and smart water meters. While some devices are designed for individual use, others work together as an integrated system. The Waltr ecosystem exemplifies this approach, offering both flexibility and comprehensive automation.
Waltr’s ecosystem includes multiple devices like Waltr A, Waltr B, Waltr C, Waltr V, and Waltr Q, but the integration of Waltr A, C, and V forms the heart of a fully automated, reliable, and efficient water management system. Users don’t need to manually configure complex setups as the system handles everything automatically. Whether for a large apartment complex or a small home, this ecosystem eliminates the stress of managing water systems manually.
In this blog, we’ll explore how Waltr A, C, and V work individually and together to create a seamless automated water management system. You’ll see why this ecosystem is recognized as one of the most advanced smart water management solutions globally.
What are Waltr A, Waltr C, and Waltr V, and how does this device work together
Waltr A (Smart Water Level Indicator): Waltr A uses advanced radar sensors to measure water levels in overhead or underground tanks with high accuracy. It fits neatly inside the tank without requiring complicated installation. The device continuously monitors water levels, inflow, and outflow, sending real-time updates to the Waltr app via Wi-Fi. This allows users to see exactly how much water is available, how much has been used, and when the tank is filling.
Waltr C (Automatic Water Level Controller): It acts as the “decision-maker” of the system. It controls the motor or pump connected to the water tank, turning it on or off automatically based on data from Waltr A. This ensures tanks are never overfilled, underfilled, or wasted due to manual errors. For setups with multiple tanks, Waltr C identifies which tank requires filling and manages pumps accordingly.
Waltr V (Intelligent Valve Controller): Waltr V manages water distribution efficiently across multiple tanks or supply lines. It works seamlessly with Waltr A and C to open or close valves as needed, ensuring water reaches the right location at the right time.
Together, these devices form a connected ecosystem: Waltr A monitors, Waltr C decides, and Waltr V executes, creating a fully automated system that functions like the “eyes, brain, and hands” of your water management system.
How the System Operates together
Step 1: Data Collection with Waltr A
Waltr A uses ultrasonic sensors fixed inside the tank to continuously detect the exact water level. These sensors measure the distance from the sensor to the water surface, giving highly accurate readings.
The raw readings are processed to calculate inflow when water is added, outflow when water is used, and the remaining capacity of the tank at any moment.
Once calculated, this information is instantly transmitted to the Waltr app through a wireless connection, so users can see live updates from anywhere.
At the same time, every reading is securely stored in the system, and over time the stored data is analyzed to reveal usage patterns, detect wastage, and guide smarter water management decisions.
Step 2: Decision Making with Waltr Software and Waltr C
The readings from Waltr A are received by the Waltr software, where they are analyzed to check the present water level in each tank.
Once the tank level drops below a set point, the software signals Waltr C to switch the pump on.
As the tank fills, Waltr A continues sending live updates, and the software keeps monitoring until the full mark is reached.
When the tank reaches full capacity, the software commands Waltr C to stop the pump immediately, preventing overflow.
In cases where there are multiple tanks, the software compares the live readings of each tank and decides the filling order, ensuring that tanks with higher demand or lower levels are given priority.
Step 3: Distribution Control with Waltr V
Waltr V begins by receiving continuous inputs — water level updates from Waltr A and pump activity updates from Waltr C. This allows it to know both the demand (which tank needs water) and the supply (whether the pump is running).
Using this information, it determines the exact tank that requires filling at that moment. If multiple tanks are in use, it checks which one is at the lowest level or most critical for supply.
Once the decision is made, Waltr V activates the corresponding valve, opening the path for water to flow into that particular tank, while keeping all other valves closed.
During the filling process, Waltr V does not remain static — it continues to monitor water level changes in real time. If one tank is full, it immediately closes that valve and can redirect water to the next tank that needs it.
This ongoing cycle of monitoring and switching ensures that water is always distributed to the right place at the right time, without requiring any manual checks or adjustments.
The Smart Architecture Behind Waltr
Modular Design for Flexible Use
The true strength of the Waltr ecosystem lies not only in the individual devices but in how they are designed to work together as a unified, intelligent platform. Each device, Waltr A, C, and V, can operate independently or as part of the integrated ecosystem. For smaller setups, Waltr A can monitor a single tank on its own, providing real-time updates and insights without requiring any other devices. In more complex installations, the devices work together seamlessly to manage multiple tanks, pumps, and valves, ensuring smooth operation across the entire system. This flexibility allows the Waltr ecosystem to scale effortlessly, whether it is deployed in a single home, a commercial office, or a large apartment complex with multiple water sources.
Intelligent Automation for Safe and Efficient Operation
Automation is at the heart of Waltr’s architecture. The system responds intelligently to real-time conditions detected by the sensors in each device. It coordinates multiple pumps simultaneously, even if they have varying capacities, and ensures that water is directed where it is needed most. At the same time, strict safety rules are embedded into the logic, so infrastructure is protected: pipes and pumps are never overworked, tanks do not overflow, and water is never wasted unnecessarily. This automated intelligence removes the need for manual monitoring, making water management both efficient and safe.
Robust Technical Framework
Behind the scenes, Waltr relies on a robust technical framework to ensure seamless operation. Cloud-based processing using AWS Lambda allows the system to evaluate hundreds of conditions before executing any action. By being event-driven rather than timer-based, the system reacts to real conditions rather than following rigid schedules. If a tank is running low, the pump is activated automatically, and if a valve or device fails, fallback mechanisms ensure water delivery continues uninterrupted. This combination of intelligent logic and technical resilience ensures that the system remains reliable even in challenging conditions.
Energy-Efficient Operation
Energy efficiency is an integral part of the Waltr architecture. Devices like Waltr A and V operate on battery power and use a smart wake-sleep cycle to conserve energy. They wake every few minutes to execute commands and then return to low-power mode, ensuring long battery life and minimal maintenance without compromising responsiveness.
Event-Based Control for Precision and Safety
The event-based control system enhances both safety and flexibility. Every command issued to the devices includes both the action and the stop condition, so even if connectivity is temporarily lost, the system knows exactly when to stop pumping. This reduces installation time, eliminates the need for complex manual setup, and allows the system to adapt safely to variations in water flow rates. Coupled with real-time monitoring and alerts delivered through the Waltr app, users always have visibility and control, with instant notifications for leaks, motor overrun, or abnormal tank levels, and access to historical data for analyzing water usage patterns.
Comprehensive Smart Architecture
Together, these elements—the modular design, intelligent automation, advanced technical framework, energy-efficient operation, event-based control, and real-time monitoring—form the smart architecture behind Waltr. This architecture ensures that Waltr A, C, and V operate as a cohesive, intelligent, and highly reliable water management ecosystem, capable of handling the complexities of modern water systems while providing users with peace of mind and complete control.
