In industrial liquid level control systems, installation stability and reliable switching performance are essential for safe and efficient operation. The stainless steel flange mounted float level switch is specifically designed for industrial tanks, pressure vessels, and process systems that require strong mechanical installation and accurate liquid level monitoring.
ELECALL offers both single-ball and double-ball flange mounted float switches, providing flexible solutions for simple ON/OFF control and advanced high/low liquid level management.
Why Choose a Flange Mounted Float Switch?
Compared with threaded float switches, flange mounted designs provide stronger mechanical support and better sealing performance in large tanks or industrial environments.
The flange structure offers several advantages:
- More secure installation for large containers and industrial tanks
- Better sealing performance under pressure conditions
- Improved structural stability under vibration or liquid turbulence
- Easier integration into industrial piping and automation systems
Flange-mounted float switches are widely used in industries such as water treatment, petrochemical processing, boilers, and industrial automation systems.
Working Principle
Both single-ball and double-ball models operate using a magnetic reed switch mechanism inside a stainless steel rod.
As the liquid level changes, the float moves vertically along the rod. The magnet inside the float activates the internal reed switch, generating a stable ON/OFF signal used for:
- Pump control
- Liquid level alarms
- Valve automation
- High/low level protection systems
Reed switch float technology is widely used because of its simple structure, long electrical life, and stable switching performance.
Stainless Steel Construction Advantages
The float and rod are manufactured from stainless steel (304 or optional 316 stainless steel), providing:
- Excellent corrosion resistance
- High mechanical strength
- Long service life in industrial environments
- Resistance to water, oil, and many chemical liquids
Stainless steel float switches are commonly used in water treatment, chemical processing, drainage systems, and industrial liquid monitoring applications.
Single-Ball Flange Mounted Float Switch
The single-ball version is designed for single-point liquid level detection. It provides a simple and cost-effective solution for applications requiring one switching point.
Its structure is compact and reliable, making it ideal for:
- Basic tank level monitoring
- Pump start/stop control
- Water storage systems
- General industrial liquid control
Because only one float is used, the system logic remains simple while maintaining stable and reliable operation.
This version is especially suitable for users who need straightforward automation with minimal maintenance requirements.
Double-Ball Flange Mounted Float Switch
The double-ball version features two independent floats mounted on the same stainless steel rod, enabling dual-point liquid level control.
This allows functions such as:
- High and low liquid level monitoring
- Overflow protection
- Dry-run protection for pumps
- Liquid level range control
Compared with the single-ball version, the double-ball design offers improved automation capability and better process safety, especially in industrial systems where liquid levels fluctuate continuously.
It is commonly used in:
- Industrial process tanks
- Chemical storage systems
- Boiler water control systems
- Automated liquid management systems
Single Ball vs Double Ball: Key Differences
| Feature | Single-Ball Version | Double-Ball Version |
|---|---|---|
| Number of switching points | 1 | 2 |
| Control function | Basic ON/OFF control | High/low level control |
| System complexity | Simple | More advanced |
| Automation capability | Standard | Higher |
| Application type | Basic storage systems | Industrial automation systems |
| Liquid management precision | Standard | More precise |
