AquaFlow is an automatic water level controller for overhead and underground tanks. It reads the level, confirms the valve, runs the pump and stops it on its own, at the site — for homes, housing societies and industrial sites, from one tank to a campus. Overflow control and dry-run protection are built in, not bolted on.

INTERACTIVE SYSTEM SIMULATION
Watch the control logic, not a cartoon.
Trigger a refill demand and follow the same disciplined sequence a professional automation system should communicate: detect, verify, actuate, confirm, authorize, monitor and shut down. Then try to break it.

PLATFORM CAPABILITIES
Built around the problems that cost water, time and motors.
Every function has a practical job: automate filling, protect equipment, reduce waste, expose consumption and make the site visible without turning it into a complicated control room.
Dashboard / hub mode and water pathLIVE OVERVIEW
Live site view
Tank levels, valve positions and pump state on one screen, with a live schematic of the whole site. When data is old, the app says so.
Alerts where you read them
Pump trips, valve faults, low sources and lost links reach you on Telegram and by email, and stay visible in the app.
Automatic filling
Tank levels and priorities decide which tank fills next. The controller at the site starts and stops the pump, so nobody has to switch it by hand.
Pump protection
Dry-run and overcurrent trips at the Pump Guard. Your starter's overload relay stays in circuit and remains the primary overload and phase-loss protection.
Overflow control
Target levels stop the pump at full instead of letting it run until someone notices.
Live tank levels
Full sensors show percent and litres. Float tanks show Empty, Low, Mid or Full. Valve position is confirmed, and pump state is shown in words.
Honest status
When data is old, the app says how old it is instead of showing a green tick. A silent controller or a lost node is shown as exactly that.
Updated over the air
Controller and node firmware is updated over the air by Gizmo.
THREE MODES
Automatic. App control. Local manual.
The controller at the site is always in one of three modes, and the app shows which one. Changing the mode needs a password confirmation.
Automatic
The controller fills the tanks by level and priority and runs the pumps. Nobody has to be there, and nobody has to be online.
App control
Pumps and valves move only when an authorised user asks from the app: run a pump for a set time, or open or close a valve. The controller checks every request and can refuse it.
Local manual
The switch at the panel is in charge and the app only watches. It works with every AquaFlow device switched off.
Stop is always there.
Stop is available to every customer from the app, at any time. A request to run is different: before the controller acts on it, it checks the tank (full), the source (low), the pump (fault) and the valve (fault), and it can refuse. Local manual, the switch at the panel, always works.
THE APP
Real screens from the current app.
These are screenshots of the AquaFlow app running on a reference site. Each one shows a specific operating task.
01Every tank at a glance: Full sensors show % and litres, float tanks show Empty, Low, Mid or Full
02Water path: each source, the pump that moves its water, and the tanks it fills in priority order, with the valve on each line

TanksLIVE LEVELS
Each tank shows its level, size and when it last reported. Full sensors give percent and litres; float tanks show Empty, Low, Mid or Full.
Water pathSOURCE TO TANK
Each source, the pump that moves its water, and the tanks it fills in priority order, with the valve on each line and its confirmed position.
MOTOR HEALTH AND APP CONTROL
See the motor. Stop it any time.
Every pump card has a Stop button and shows motor current, temperature and vibration. The hub can be switched to App control.
PumpsMOTOR HEALTH
Real-time motor current, temperature and vibration are monitoring only: these readings never stop a running motor. An optional per-pump switch refuses a new start when the motor is hot. In Automatic mode, Stop also keeps the pump from restarting for 30 minutes.
App-operated outletAPP CONTROL MODE
An outlet with no level sensor, such as a fountain, runs for a set time you choose and can be stopped at any time. The time limit is its only protection, so the controller caps it (30 minutes here). The controller at the site checks every request and can refuse it.
ARCHITECTURE
Modular at the site. Clear in the interface.
Four devices, one system. Take one of each for a simple site, or add more as the site grows.
Site Controller
Holds the site’s signed configuration and decides which pump fills which tank, and when. Connects to the cloud over Wi-Fi, with a 4G option. A battery ride-through is designed in for power cuts.
Tank Node
Measures the level in each tank: a hydrostatic sensor for level in % and litres, or float steps for a simple Empty / Low / Mid / Full. Solar option where no supply reaches the tank.
Valve Node
Opens and closes a motorised valve and confirms that it actually moved, from the valve’s limit switches. A stuck valve is reported, not ignored.
Pump Guard
Closes your starter’s coil circuit; it never switches motor power. Watches motor current on 1 or 3 phases, and motor temperature and vibration with its sensor head.
Pump Guard drives your starter, not your motor
Pump Guard never switches motor power. It closes the control coil of your existing starter, with your starter's overload relay always in the circuit. The overload relay remains the primary overload and phase-loss protection; Pump Guard adds dry-run and overcurrent trips.
MULTI-TANK VISIBILITY / ILLUSTRATION
One site. Every tank. One operating picture.
AquaFlow is designed to scale from a single installation to multiple tanks and zones, with the site presented as a coherent system rather than disconnected devices.

SAFETY ARCHITECTURE
Safety is an architecture, not an icon.
The system separates fallback, local protection, operating rules and cloud visibility so the most important protections do not depend on a single network path.
Designed to fail safely.If a required condition is not confirmed, the sequence does not blindly continue.
Pump Guard never switches motor power. It closes and opens the control coil of your existing motor starter, with your starter's overload relay always left in the circuit.
Stop is available to every customer from the app at any time. In App control mode, authorised users can run a pump for a set time or open and close a valve, and the controller at the site checks every request (tank full, source low, pump fault, valve fault) and can refuse it. In Automatic mode the controller runs everything by level.
Local manual, the switch at the panel, always works, and the app only watches.
What AquaFlow does not measure: supply voltage, phase angle or power factor, and water pressure. Any power figure in the app is an estimate, not a meter reading.

QUESTIONS
Water level controller questions, answered plainly.
What is AquaFlow — a water level controller or a pump controller?
Both. AquaFlow reads the tank level, confirms the valve, runs the pump and stops it on its own, at the site. One system covers a single overhead tank, a sump-plus-overhead pair, or a multi-tank housing society or campus.
Is it wireless between the tank and the pump?
Yes. The tank sensor talks to the pump controller over a long-range radio link, so no cable needs to run from the terrace to the pump room. If the link drops mid-fill the pump stops itself and does not re-arm until the link is back and confirmed.
Does it protect against dry run and overflow?
Yes. The pump is never started without a confirmed valve and a valid level reading, and it is stopped at the full mark. The Pump Guard trips on dry-run and overcurrent. Your starter's overload relay always stays in circuit and remains the primary overload and phase-loss protection.
Can I start or stop the pump from the app?
You can always stop it: Stop is available to every customer from the app at any time. In App control mode, authorised users can run a pump for a set time or open and close a valve. The controller at the site checks every request (tank full, source low, pump fault, valve fault) and can refuse it. In Automatic mode the controller runs everything by level. Local manual, the switch at the panel, always works and the app only watches.
What pump sizes and starters does it support?
Any pump runs through Pump Guard, single- or three-phase. Pump Guard drives the control coil of your existing starter and leaves your overload relay in circuit. Listed motor range is 0.5–20 HP.
How much does an automatic water level controller cost?
Hardware, installation and service are quoted per site after a free site assessment, because the price depends on the number of tanks, pump HP, starter type and the distance between tank and pump. Share those four details and you get a same-day quote.
Where do you install?
We install in Pune and supply across India. Homes, housing societies, irrigation and industrial sites.
