Automatic Float-Less Water Level Controller for Single & Double Tanks (10A No-Volt Contact Output )

Smart & Automated Water Management for Homes & Commercial Buildings

Forgetting to turn off the water motor leads to massive water wastage, high electricity bills, and roof seepage. Conversely, running a pump dry when the underground tank has no water can burn out the pump motor.

The Multilec Float-Less Automatic Water Level Controller Series provides a completely hands-free solution for smart water management. By utilizing electronic sensor probes instead of failure-prone mechanical floats, it accurately senses real-time water levels and operates the pump automatically with zero manual intervention.

🎛️ Choose Your Ideal Model

• 1️⃣ Model WLC-3S (Single Tank System):

  • Engineered for setups with a single overhead or underground storage tank.

  • Automatically switches the pump ON when the tank drops below the minimum level and switches it OFF as soon as the tank reaches full capacity.

• 2️⃣ Model WLC-2D (Double Tank System – Underground + Overhead):

  • Designed for dual-tank systems where water is pumped from an underground suction tank to a rooftop overhead tank.

  • Synchronizes both tanks: automatically refills the overhead tank while continuously checking the underground tank level to provide total Dry-Run Motor Protection.

✨ Key Features & Technical Highlights

• 🌊 Float-Less Sensor Technology: Uses rust-free, stainless sensor probes instead of bulky mechanical float switches that frequently stick, rust, or fail over time.

• ⚡ 10A No-Volt Cut Contact Output: Features clean dry-contact (no-volt) output switching rated up to 10 Amps, allowing seamless interfacing with magnetic contactors, starters, or direct motor loads.

• 🛡️ Built-In Dry-Run Safety: Automatically halts the motor if the source tank runs out of water, shielding your pump impeller and motor windings from burning out.

• 🧠 Microcontroller Precision: High-speed response logic prevents false triggers caused by water sloshing or ripples inside the tank.

• 🔌 Repairable & Durable Design: Built with industrial-grade replaceable components ensuring long operational lifespan and easy long-term maintenance.

📺 Ideal For Devices & Applications

• Submersible Water Pumps & Turbine Motors

• Single-Phase Domestic Suction Pumps

• Overhead Roof Tanks & Underground Storage Sumps

• Commercial Buildings, Apartments, Factories, and Farms

💚 Multilec Water Controller Lagane Ke Faide (Benefits)

1. 💰 Electricity & Water Saving: Motor overflow ko 100% khatam karke bijli ke bill aur paani ki bachat karta hai.

2. 🔄 Completely Hands-Free: Motor ko khud ON/OFF karne ki zaroorat nahi rehti—system 24/7 automatic kaam karta hai.

3. 🚫 No Mechanical Wear & Tear: Float-less sensors hone ki wajah se koi mechanical ball stuck nahi hoti aur zang (rust) nahi lagta.

4. 🛡️ Motor Burnout Protection: Dry-running protection ki wajah se motor paani ke bina nahi chalegi, jis se lakhoon rupay ki motor tabah hone se bach jati hai.

⚠️ Automatic Controller Na Lagane Ke Nuqsanat (Risks)

• ❌ Tank Overflow & Seepage: Tanki bhar kar behne se roof slabs, chhat ki plaster, aur deewaron mein seepage (seem) paida hoti hai.

• ❌ Motor Dry-Running Burnout: Neche wali tanki mein paani khatam hone par agar motor chalti rahe toh motor 10-15 minute mein jall sakti hai.

• ❌ Excessive Electricity Bills: Motor ka faltu chalna monthly electricity bills mein izafay ka sabab banta hai.
