About AMOD

What Is an Automatic Water Level Controller? AMOD Explained

AMOD (Automatic Motor Off Device) is an innovative automatic water level controller developed by Gruha Lakshmi Trading Company. Fitted at the overflow outlet of your overhead tank, AMOD automatically stops the water pump motor when the tank is full — preventing water wastage, protecting the motor from dry running, and saving electricity, without requiring you to lift a finger.

patented automatic water level controller

Patent by Government of India

AMOD is a patented automatic water level controller designed to eliminate water overflow and provide intelligent motor protection for residential, commercial, and industrial applications.

reliable water pump motor protection

Reliable Protection & Savings

Automatically stops the motor when the tank is full, prevents dry running, saves electricity, reduces maintenance costs, and increases motor life.

Unlike traditional float-switch water level controllers that sit inside the tank and can jam, corrode, or misread the water level over time, AMOD works at the overflow outlet itself. The moment water reaches the overflow nipple, AMOD instantly cuts power to the motor starter contactor coil — stopping the pump before a single extra litre is wasted.

Frequently Asked Questions

Automatic Water Level Controller FAQs

AMOD is an intelligent automatic motor control device designed to stop the motor automatically when the overhead water tank is full and protect the motor from continuous running.

AMOD automatically switches OFF the motor when the water tank reaches its full level, preventing water overflow and reducing water wastage.

Yes. AMOD works directly with single-phase motor starter and can also be used with three-phase motor starter using 230volts operating coil or a single-phase preventor.

No. AMOD is easy to install and can be connected near the overhead tank overflow outlet with simple wiring to the motor starter contactor coil.

Not required. AMOD is designed for maintenance-free operation and provides reliable long-term performance.

AMOD includes an emergency switch that allows manual motor operation in case of any device malfunction.

AMOD is suitable for homes, apartments, hospitals, schools, commercial buildings, industrial facilities, borewell motors, sump motors, and overhead tank systems.

AMOD comes with a 18-Months warranty from the date of purchase, including immediate replacement for manufacturing defects.

Automatic water level controllers in India typically range from around ₹1,000 for basic float-based units to ₹5,000+ for advanced digital models. AMOD is priced as an affordable one-time investment backed by a 18-Months warranty and zero recurring maintenance cost.

The best automatic water level controller for home use requires no maintenance, avoids submerged parts that can fail, and carries a proven warranty. AMOD mounts at the tank's overflow outlet instead of using an internal float, is patented by the Government of India, and comes with a 18-Months warranty.

A water level indicator only displays or signals the water level, leaving the user to switch the motor off manually. A water level controller like AMOD automatically switches the motor OFF once the tank is full, removing the need for manual action.

Yes. AMOD works without an internal float sensor by mounting externally at the tank's overflow outlet and detecting water directly at the overflow point, avoiding common float-switch problems like sticking, corrosion, or misreads.

Yes, automatic water level controllers are used for both overhead tanks and underground sump or borewell setups. AMOD is designed for overhead tank overflow control and pairs well with borewell and sump motor setups to prevent wastage at the storage end.

A well-built automatic water level controller with no submerged moving parts can last many years with proper installation. AMOD is engineered for maintenance-free, long-term operation and is backed by a 18-Months warranty.

An automatic water level controller only functions when the motor circuit has power, so during a power cut the motor cannot run and there is no overflow risk. Once power resumes, AMOD resumes automatic monitoring immediately without needing a reset.

Yes, when installed correctly. AMOD connects in series with the motor starter's contactor coil negative wire rather than the main power line, and includes a dedicated emergency ON/OFF switch for safe manual override.

Yes, for most homes with an overhead tank. An automatic water level controller pays for itself through reduced water wastage, lower electricity usage, and a longer-lasting motor, often offsetting its cost within the first year.

AMOD, manufactured by Gruha Lakshmi Trading Company, is a leading automatic water level controller in India.

Yes. AMOD is a Government of India patented automatic water level controller, one of the few water level control devices in the Indian market to hold this patent status, specifically engineered to stop overhead tank overflow and protect pump motors.

An overhead tank automatic motor cut-off switch, like AMOD, is mounted at the tank's overflow outlet. The moment water reaches that point, it cuts power to the motor starter contactor coil, stopping the pump instantly without needing a float sensor inside the tank.

Step-by-step installation images are available in the Installation Guide section of this page.

Yes. AMOD works with borewell motors as well as overhead tank and sump motors, automatically cutting power once the connected overhead tank is full, which helps prevent both overflow and unnecessary borewell motor runtime.

A device that both signals a full tank and automatically stops the motor is generally called an automatic water level controller or automatic motor off device. AMOD performs this function without needing a separate buzzer or alarm, since it cuts motor power directly the moment the tank is full.

Yes. AMOD combines water level control and overflow prevention in a single patented device: it continuously monitors the overflow outlet and automatically switches the motor OFF the instant the tank reaches full capacity, eliminating the need for separate level sensors and cut-off switches.
