Wiring diagram

What is an adjustable float level switch used for?

This float switch is used for liquid level detection and automatic control in tanks, containers, and industrial systems. It can control: Pumps Alarms Solenoid valves Liquid level monitoring systems Adjustable models allow users to manually set the switching position, making them more flexible than fixed models.

What is the key advantage of an adjustable float switch?

The main advantage is adjustable switching position. Users can change: Trigger position Control height This makes it ideal for: Different tank sizes Custom liquid level requirements Flexible installation conditions

What material is the float switch made of?

The float and rod are made of SU304 stainless steel, offering: Corrosion resistance High temperature resistance Strong mechanical strength Long service life For more demanding environments, 316 stainless steel customization is available.

Is it normally open (NO) or normally closed (NC)?

It supports both Normally Open (NO) and Normally Closed (NC), depending on the float orientation. The switching logic can be changed by reversing the float by 180°. Lower-Open Type (Default) ① When the liquid level rises, the float moves away from the reed switch position, and the switch turns OFF. ② When the liquid level falls, the float returns to the reed switch position, and the switch turns ON. Upper-Open Type ① When the liquid level rises, the float returns to the reed switch position, and the switch turns ON. ② When the liquid level falls, the float moves away from the reed switch position, and the switch turns OFF. Note The factory default is usually the lower-open type, but users can adjust it according to control requirements.

Can it directly control pumps or solenoid valves?

No. Because the internal reed switch carries only a small current, it must be used with: Relay Contactor Otherwise, the contacts may burn.

Can the float position be adjusted freely?

Adjustable model: YES (within range) Unlike fixed models, this product allows users to adjust the float position along the rod. However: Adjustment range is limited Internal reed switch position is fixed

What liquids is it suitable for?

Suitable for: Water Light oil Industrial liquids Not recommended for: Heavy sludge High debris liquids

Can it be customized?

Yes. Available customization: Rod length Thread size Cable length Float quantity Material (304 / 316)

What should buyers confirm before purchasing?

Buyers should confirm: Liquid type Temperature Pressure Installation method Thread size Rod length Cable length NO / NC Quantity Custom requirements

Why choose a single-ball adjustable model?

Choose single-ball if: Space is limited Only one control point needed High sensitivity required Fine adjustment needed
