What is the UQK stainless steel flange float level switch used for?

The UQK stainless steel flange float level switch is used for liquid level detection, monitoring, and automatic control in industrial tanks and vessels. It is widely used in: Water tanks and reservoirs Chemical tanks Oil tanks Sewage and wastewater systems Industrial automation equipment Pump control systems Boiler and heating systems It can provide high-level alarm, low-level alarm, overflow protection, and pump start/stop control.

What is the main feature of the UQK series?

The UQK series uses a flange-mounted stainless steel structure, offering: Strong and stable installation Suitable for large tanks and industrial equipment Reliable sealing performance High mechanical strength Long service life It is especially suitable for industrial liquid level control applications.

What materials are used in the float switch?

The float ball, rod, and flange are made of stainless steel (typically SU304). Advantages include: Corrosion resistance High temperature resistance Strong durability Suitable for industrial liquids 316 stainless steel versions may be available for corrosive media.

How does the float level switch work?

The switch uses a magnetic float and reed switch principle. When the liquid level changes: The float moves with the liquid The internal magnet approaches the reed switch The reed switch opens or closes the circuit This creates an ON/OFF control signal for liquid level automation.

Can it directly control pumps or solenoid valves?

No — not recommended for direct load switching. The internal reed switch is designed for low-current signal applications and should not directly control inductive or high-power loads such as pumps or solenoid valves. Recommended solution: Control signal → relay or PLC input Pump or valve → relay / contactor / motor starter ⚠️ In low-power applications (small DC pumps or low-current valves), direct switching may be possible only if the load is within the switch rating. Direct connection may reduce lifespan or damage the reed contacts.

Is it suitable for high-temperature or corrosive environments?

Yes. The stainless steel structure provides: Good corrosion resistance High temperature resistance Stable performance in industrial environments For stronger corrosion resistance, 316 stainless steel is recommended.

Can the rod length and float quantity be customized?

Yes. Customization options include: Rod length Float quantity Flange size Mounting dimensions Cable length OEM / ODM production This allows compatibility with different tank structures and project requirements.

What liquids is it suitable for?

Suitable for: Water Oil Industrial liquids Chemical liquids compatible with stainless steel Wastewater and sewage Not recommended for: Heavy sludge High-viscosity liquids with severe buildup

What are the advantages of flange mounting?

Flange mounting provides: Stronger mechanical support Better sealing for large tanks Easier installation in industrial equipment Suitable for high-pressure or large-volume systems Better long-term stability

What should buyers confirm before ordering?

Before purchasing, buyers should confirm: Liquid type Working temperature Working pressure Required rod length Float quantity Flange standard and size Installation direction NO / NC logic Electrical specifications Quantity and customization requirements This helps ensure proper installation and system compatibility.
