Fully Automatic Water Level Controller with Dry Run Protection
Overview
The Fully Automatic Water Level Controller Circuit Board with Dry Run Protection for Monoblock Pumps is a compact and affordable solution for automatic water management. It is designed with magnetic float switches and a step-down transformer-based circuit, making it both efficient and safe to use.
How It Works
The controller automatically switches ON the motor when the water level falls below the bottom sensor. Likewise, it turns OFF the motor once the tank reaches the top level. In addition, it includes dry run protection that shuts off the pump when no water flow is detected, preventing motor damage.
Key Features
Automatic operation: Starts and stops the pump according to water levels.
Dry run safety: Prevents damage when there is no water supply.
LED indicators: Shows top, bottom, flow, power, and motor status.
Manual override: Semi-automatic and manual/auto switch options available.
Safe design: No current passes into the water, avoiding corrosion and chemical reactions.
Compact build: The board measures only 9.5 cm × 6.5 cm, which makes installation simple.
Why Choose This Controller?
Unlike manual monitoring, this board saves time, water, electricity, and motor life. It works with normally open float switches, ensuring reliable performance without complicated setup. Moreover, it is suitable for both households and commercial setups where water supply automation is essential.
Technical Requirements
Transformer: 12V to 18V, 1A step-down transformer.
Float switches: Two magnetic float switches (NO type) are required for top and bottom level sensing.
Dry run sensor: Optional but highly recommended for maximum motor protection.
Relay: Includes a 12V, 30A relay to handle pump load effectively.
Benefits at a Glance
Prevents overflow and wastage of water.
Protects pump against dry running.
Ensures long life of the motor.
Reduces electricity bills by avoiding unnecessary pump usage.
Provides continuous status updates with LED indicators.
Frequently Asked Questions (FAQ)
1. Can I use this board without a dry run sensor?
Yes, the board will still function without the dry run sensor. However, for maximum protection of your motor, it is recommended to connect the dry run sensor.
2. What type of transformer should I use?
You will need a 12V to 18V, 1A step-down transformer for proper operation of the board.
3. Does this controller work with all pumps?
It is mainly designed for monoblock pumps, but it can also work with small household motors that operate through float switches and relay control.
4. How many float switches are required?
The system requires two magnetic float switches (normally open type) – one for the bottom level and one for the top level. An additional sensor can be used for dry run protection.
5. Is it safe to use in water tanks?
Yes. This board is completely safe because no current passes into the water. It uses magnetic float switches, so there is no corrosion or chemical reaction in the tank.
6. Can I switch the motor on manually?
Yes, the board comes with a manual/auto switch option and a device on/off switch, giving you complete control when needed.
7. What is the size of the board?
The board is approximately 9.5 cm × 6.5 cm, making it compact and easy to install in most setups.
8. Can I use Cable floats?
Yes. 230v cable floats can be used. In this case, we can use either top or bottom led only.
