Smart Care Systems – Microcontroller-Based Automatic Water Level Controllers

Smart Care Systems offers microcontroller-based automatic water level controllers with features like dry-run protection, voltage cut-off, and heavy-duty relays, marketed as “absolutely maintenance-free” due to their durable sensors. These systems are designed for reliable, automated water tank management and claim a sensor life of over 10 years.

Product Features and Specifications

Smart Care Systems emphasizes advanced technology for hands-free operation and motor protection.

Advanced Microcontroller Technology: The devices use an intelligent microcontroller design for accurate detection of water levels, fault identification, and timely actions.
Comprehensive Motor Protection: Built-in features include dry-run protection (shuts off motor if no water flow is detected), high/low voltage cut-off (operating range typically 160V to 260V AC), and surge protection.
Heavy-Duty Relays: The controllers feature high-capacity relays, often 30 Amp, suitable for motors up to 2 HP (single-phase).
Sensor Technology: The systems use high-grade, corrosion-free SS (stainless steel) or carbon sensors, designed for long life and minimal cleaning. AC sensing is used to prevent sensor polarization.
Versatile Compatibility: Models are available for single-phase/borewell pumps and support multi-pump/multi-tank configurations.
Operating Modes: Most units offer fully automatic, semi-automatic, and manual modes for flexible control.

“Maintenance-Free” Design and Sensor Life

The claim of an “absolutely maintenance-free system” with “More Than 10 Years Sensor Life” is a key selling point, based on specific design choices.

Corrosion-Free Sensors: Unlike standard sensors that may corrode or accumulate mineral deposits over time, the high-grade SS316 or carbon sensors are designed to resist rust and corrosion, reducing the need for frequent cleaning or replacement.
AC Sensing Feature: Using a low AC voltage sensing circuit prevents the polarization of electrodes in the water, which is a common issue leading to sensor failure or inaccurate readings in other systems.
No Mechanical Movement: The use of static conductive sensors (instead of mechanical float switches which can wear out) eliminates moving parts in the water tank, contributing to longevity and reliability.

While these features significantly minimize routine maintenance, general best practices still recommend occasional inspection of wiring and the control unit location to ensure longevity and safety.

Frequently Asked Questions

What is an automatic water level controller?

It is an electronic device that automatically turns your water pump ON when the tank level is low and OFF when the tank is full. This prevents overflow, dry-run and saves time and electricity.

Do Smart Care Systems controllers have dry-run protection?

Yes. All models include dry-run sensing logic that detects when there is no water at the source and switches the motor OFF to protect it.

Are these controllers suitable for borewell pumps?

Yes. ULDX models are suitable for many borewell and openwell pump installations used in homes, farms and small industries.

How long does installation take?

A qualified electrician can typically install and wire the controller in about 1-2 Hours, depending on the existing wiring and starter arrangement.
