This float switch is mainly used for liquid level detection and automatic control in tanks, water reservoirs, chemical containers, oil tanks, sewage treatment systems, and industrial automation equipment. It helps control pumps, alarms, solenoid valves, and level monitoring systems. ELECALL side-mounted stainless steel float switches are commonly applied in water treatment, petrochemical, metallurgy, and industrial tank systems.

The standard model uses SU304 stainless steel, including both the float ball and the float body, which provides: Excellent corrosion resistance High temperature resistance Strong mechanical strength Long service life Suitable for water and many industrial liquids For stronger corrosion resistance, some applications may also require 316 stainless steel customization. The product page also mentions available options in both 304 and 316 stainless steel.

It supports both. The float ball can be manually reversed by 180° rotation, allowing users to switch between: Lower-open state Upper-open state Factory default is usually the lower-open setting. This gives buyers more installation flexibility depending on control logic requirements.

No. Because the internal reed switch carries only a small current, it should not directly control high-power loads such as: Water pumps Solenoid valves AC contactors Large alarms Recommended solution: For alarms or solenoid valves → use a small relay (such as HH54P / HH52P) For water pumps → use relay + AC contactor Direct connection may burn the reed contacts.

The control stroke is usually 10mm, which means it is highly sensitive and suitable for precise liquid level detection. If a larger liquid level difference is required, buyers can choose: Two single-ball switches installed at different heights One double-ball float switch This improves level control range.

Yes. ELECALL supports: Rod length customization Thread size customization Float quantity customization Special mounting requirements OEM / ODM production This is especially useful for distributors, equipment manufacturers, and project buyers. ELECALL also highlights OEM/ODM support and low MOQ sourcing.

Not recommended. Because the reed switch stroke is small and highly sensitive, it performs best in: Clean water Light industrial liquids Low-viscosity media For liquids containing: Floating debris Heavy sediment Thick sludge buyers should consider more heavy-duty float switches or cable float switches.

No. The float ball position is fixed by circlips, and the internal reed switch position cannot be moved. Simply moving the circlips will not change the switching point effectively. If special switching positions are required, buyers should request customized dimensions from the manufacturer.

Before placing an order, buyers should confirm: Liquid type (water / oil / chemical / wastewater) Working temperature Working pressure Installation direction Mounting thread size Rod length Required cable length NO or NC logic Voltage/current requirements Quantity and customization needs Clear specifications help avoid installation problems later.

Yes. ELECALL is a professional industrial measurement and control manufacturer founded in 2008, providing: CE / ROHS certified products OEM / ODM customization Factory-direct pricing Low MOQ Export support Distributor cooperation This makes them suitable for wholesalers, importers, and industrial system integrators.

Choose single-ball if: Space is limited Precise point-level detection is needed Compact installation is required Choose double-ball if: Larger level differential is needed Pump start/stop control requires wider range More stable switching is preferred The application scenario determines the better choice.
