Accurate and reliable liquid level measurement is critical across industries, from household appliances and water treatment to industrial automation and chemical processing. ELECALL offers a wide range of high-quality level switches, float level switches, level transmitters, and controllers designed to meet diverse application needs with excellent durability, flexibility, and cost-effectiveness.
The Level Product Category on ELECALL’s website showcases a complete portfolio of liquid level control solutions, primarily based on proven float switch technology, along with advanced electronic and ultrasonic options.
1. Stainless Steel Float Level Switches
ELECALL provides a full series of robust stainless steel float level switches made from 304 or 316 stainless steel, offering superior corrosion resistance and suitability for water, oils, weak acids/alkalis, and many industrial liquids.
Key Products Include:
- Single Ball & Double Ball Adjustable Stainless Steel Float Switches These vertical-mount switches feature adjustable float positions, allowing users to easily set one or two control points (high/low level) according to tank requirements. Ideal for precise level control and pump automation.
- Side Mount Stainless Steel Float Level Switches (Single Ball & Double Ball) Designed for side installation using an elbow pipe structure, these are perfect for tanks with limited top space or internal obstacles. The double-ball version provides wider control differential for more stable pump operation.
- Straight Rod Stainless Steel Float Level Switches (Single & Double Ball) Classic vertical stem design with reliable reed switch technology, suitable for standard tank installations.
These stainless steel models support operating temperatures from -30°C to +120°C and are widely used in water towers, boilers, wastewater systems, and industrial storage tanks.
2. Plastic Float Level Switches
For cost-sensitive and light-duty applications, ELECALL offers PP (Polypropylene) and PVDF plastic float switches.
- EP Series PP Plastic Float Level Switches Lightweight, economical, and highly buoyant with excellent electrical insulation. Suitable for water purifiers, humidifiers, coffee machines, solar water systems, and household water tanks. Operating temperature up to +85°C.
- Side-Mounted Plastic Float Switches (EPC Series) and Duckbill Side Mount Plastic Switches Compact designs for easy side installation in limited spaces.
- Duckbill Side Mount PVDF Float Level Switches (ELEC4 / ELEC6) High chemical resistance version, ideal for aggressive acids, alkalis, and corrosive environments in chemical processing and advanced water treatment.
Plastic series switches are popular for their low cost, low water absorption, and reliable performance in non-extreme conditions.
3. Specialized and Advanced Level Products
- Stainless Steel Low Density Float Level Switches for Oil and Alcohol Specially optimized for low-density liquids such as oils, fuels, and alcohol solutions.
- Cable Float Switches (High Temperature Cable Type) Suspended cable design with stainless steel floats, suitable for large tanks, sumps, and deep wells. Available in mercury switch and micro switch versions with high-temperature silicone cables.
- Magnetic Float Balls Replacement or custom components for various float switch assemblies.
- Level Transmitters Continuous level measurement solutions for real-time monitoring and analog output (4-20mA).
- Electronic Level Controllers Integrated control units that combine level detection with pump or valve control logic.
- Ultrasonic Level Transmitters Non-contact level measurement technology ideal for corrosive, viscous, or high-temperature liquids where float switches may not be suitable.
All ELECALL level products are CE and ROHS certified, with optional ATEX explosion-proof versions available for hazardous environments.
