In industrial liquid level control, side mount stainless steel float level switches are essential for tanks where top mounting is impractical due to limited space, internal agitators, or structural constraints. These switches provide accurate, reliable point-level detection and are widely used in water treatment, HVAC, household appliances, and light industrial systems.
Leading Brands in the Side Mount Float Level Switch Market
Several established international brands are recognized for high-quality side mount float level switches. KOBOLD (Germany) is well-known for its robust magnetic float switches with excellent precision and durability in industrial environments. SOR Inc. (USA) offers rugged, ASTM-grade stainless steel level switches favored in oil & gas and process industries. Rochester Sensors (USA) and National Magnetic Sensors provide highly customizable side-mount solutions, particularly for demanding applications involving vibration or harsh conditions. Other notable players include Baumer, WIKA, and Trimod’Besta, which emphasize premium materials and certifications.
These brands set high standards for reliability, but they often come with premium pricing and longer lead times. Many customers seeking a balance of performance, customization flexibility, and cost-effectiveness are turning to specialized manufacturers like ELECALL.
ELECALL Side Mount Stainless Steel Float Level Switches
Yueqing ELECALL Electric Co., Ltd. offers two highly practical configurations of side mount stainless steel float level switches: the Single Ball series and the Double Ball series. Both are engineered for side installation using an elbow pipe design, making them ideal for compact tanks and vessels.
1. Single Ball Side Mount Stainless Steel Float Level Switch (ESC Series)
The Single Ball version (models: ESC7810 to ESC120010) is designed for precise single-point level detection. It features one magnetic float ball that moves along a stainless steel stem. When the liquid level reaches the set point, the magnet activates the internal reed switch to open or close the circuit.
Key Features:
- Material: 304 stainless steel (316/316L optional for stronger corrosion resistance)
- Operating Temperature: -30°C to +120°C
- Contact Rating: 10VA (1A1) / 50VA (2A1)
- Switching Voltage: up to 220V AC/DC
- Control Stroke: Approximately 10mm (highly sensitive)
- Compact structure with laser seamless welding
- Thickened rubber gasket + epoxy resin sealing for excellent waterproof and anti-oxidation performance
- Float can be rotated 180° to switch between Normally Open (NO) and Normally Closed (NC)
This model is particularly suitable for applications requiring accurate high-level or low-level alarm or control in limited installation spaces.
2. Double Ball Side Mount Stainless Steel Float Level Switch (ESC-2 Series)
The Double Ball version (models: ESC20010-2 to ESC90010-2) incorporates two magnetic floats on the same stem, enabling dual switching points (upper and lower level control). This design provides a wider control differential, making it more suitable for automatic pump start/stop systems.
Key Features:
- Material: 304 stainless steel (316L optional)
- Operating Temperature: -30°C to +120°C
- Larger control differential compared to single ball version
- Same high-quality reed switch, laser welding, and reinforced sealing
- Better stability for systems with larger level fluctuations
- Reduces frequent pump cycling, extending equipment life
The Double Ball model excels in water supply/drainage automation, wastewater treatment, cooling systems, and applications needing both high and low level protection.
Common Advantages of ELECALL Side Mount Series
- Robust Construction: Laser seamless welding ensures strength and leak-proof performance.
- Excellent Sealing: Thickened rubber gasket and epoxy resin provide superior protection in humid environments.
- Flexible Installation: Elbow pipe design allows convenient side mounting on tank walls.
- Customization: Rod length, thread size, float spacing (for double ball), material grade (304/316), and NO/NC configuration are all customizable.
- Long Service Life: High-quality reed switch with low contact resistance and stable performance.
- Wide Applications: Water tanks, solar systems, water heaters, humidifiers, coffee machines, air conditioners, agricultural irrigation, industrial automation, and more.
Important Note: These switches are not designed to directly control high-power loads (pumps, solenoid valves, etc.). An intermediate relay is recommended for safe operation.
