The Side Mount Stainless Steel Float Level Switch is designed for high-pressure industrial tanks, offering reliable level detection in demanding environments. It features a durable 316 stainless steel construction, making it suitable for high-stress applications. The switch can be mounted horizontally through the side of the tank, using a hermetically sealed design to ensure leak resistance. It operates using a magnetic reed switch activated by the float, providing customizable normally open (NO) or normally closed (NC) configurations. This switch is ideal for applications such as chemical tanks, fuel tanks, and industrial storage tanks, where high corrosion resistance and precise level control are required.

The Side-Mount Polypropylene Float Level Switch is a specialized liquid sensing solution designed explicitly for chemical and beverage tanks, as well as industrial storage systems. Its horizontal side-mount design is engineered to simplify installation through tank walls, while its durable polypropylene (PP) housing and float are formulated to resist aggressive liquids—including acids, alkalis, syrups, and food-grade oils. This focus on chemical compatibility and easy installation addresses the unique challenges of liquid level monitoring in corrosive or FDA-regulated environments.

Equipped with a hermetically sealed magnetic reed switch, the device delivers precise level detection to prevent overflow, pump dry-run damage, and contamination—critical concerns for beverage production (FDA-compliant) and chemical processing. Unlike power-dependent sensors, it operates without external electricity, reducing energy costs and wiring complexity, making it ideal for remote tanks or off-grid applications.
Crafted from high-grade polypropylene, the switch’s housing and float offer exceptional resistance to a wide range of chemicals—from concentrated acids (e.g., hydrochloric acid) to alkaline cleaners and food-grade syrups. This corrosion resistance eliminates component degradation, extending service life and reducing maintenance costs in harsh liquid environments.
The horizontal side-mount configuration saves vertical space by installing through tank sides, eliminating the need for top-mount access. This design simplifies retrofits for existing tanks and works seamlessly with low-ceiling facilities or tanks with limited top clearance, reducing installation time and labor costs.
The internal magnetic reed switch is hermetically sealed to prevent liquid leakage and protect sensitive electrical components from moisture, chemicals, and debris. This seal ensures reliable operation in wet or corrosive environments, minimizing downtime and extending the switch’s operational life.
The switch supports both Normally Open (NO) and Normally Closed (NC) configurations, tailored to specific application needs. For example, NO setups trigger overflow alarms when liquid levels rise too high, while NC configurations activate pumps when levels drop to critical lows—providing flexible control for diverse monitoring scenarios.
Operating via buoyancy and magnetic activation, the switch requires no external power source, reducing energy consumption and eliminating the risk of electrical hazards in wet environments. This design also simplifies installation in remote locations or tanks without access to power, making it a cost-effective solution for industrial and residential applications.
In chemical processing plants, the switch tracks levels in acid/alkali storage tanks, triggering pumps to stop when levels exceed safe limits (preventing spills) or start when levels are low (avoiding pump dry-run damage). Its chemical resistance ensures compatibility with harsh reagents, reducing the risk of equipment failure.
For beverage manufacturers, the switch monitors juice, syrup, or water levels in FDA-compliant tanks, ensuring a consistent supply for bottling lines and preventing cross-contamination. Its PP construction is food-safe, and its hermetic seal prevents liquid ingress, meeting strict industry hygiene standards.
Adaptable for non-corrosive fuel tanks (e.g., gasoline, diesel), the switch provides real-time fuel level data to vehicle dashboards or fleet monitoring systems. Its side-mount design fits seamlessly into automotive tank configurations, and its durability ensures reliable performance in vehicle operating conditions.
In water treatment plants, the switch monitors reagent levels in treatment tanks, optimizing chemical dosing and ensuring compliance with environmental standards. It controls pumps to maintain consistent levels, improving treatment efficiency and reducing chemical waste.
Yes, polypropylene is highly resistant to most concentrated acids, including sulfuric acid, hydrochloric acid, and nitric acid. However, contact our team to confirm compatibility with your specific chemical, concentration, and operating temperature—some highly oxidizing acids may require specialized modifications.
The switch is designed for tank walls 5–20mm thick. For thicker walls (20–50mm), custom gaskets and mounting hardware are available to ensure a leakproof seal, preventing liquid leakage around the installation point.
Yes, the PP housing is UV-resistant, protecting the switch from sunlight degradation and ensuring durability for outdoor use—such as agricultural chemical tanks, outdoor water storage, or industrial tanks in open facilities. Its weather-resistant design withstands temperature fluctuations and precipitation without performance loss.
