Sundex 3 m Float Switch

It’s suitable for monitoring liquids such as water, oil, and gasoline. The float material is designed to be corrosion‑resistant, but always ensure the liquids are compatible with the float material and the switch’s construction before use.

Core specs include: sensing range up to 3 meters, a 3-meter long body, corrosion‑resistant float material, a compact and durable construction, and an adjustable design for tailoring the switch to your tank setup.

It’s suitable for domestic and commercial tanks such as water tanks, oil tanks, and gasoline tanks. Its compact form and corrosion‑resistant float make it adaptable to wet and humid locations as described.

General installation steps: 1) select the mounting location inside the tank where the float can move freely without obstruction, 2) mount the switch securely, 3) route and secure electrical connections, 4) adjust the switch’s position for the desired trip point, and 5) test operation by simulating level changes to ensure proper functioning.

Use the provided mounting adjustments to set the float’s travel range to your target liquid level. After positioning, retighten all fasteners and verify that the float can move freely through its full range without snagging on tank walls or fittings.

The Sundex 3 m Float Switch is designed for low maintenance. Periodically inspect for debris or buildup that could impede float movement, check for any signs of corrosion, and ensure the wiring remains secure and intact. Clean as needed and reseal connections if exposed to harsh environments.

Ensure liquids are compatible with the float material and switch construction. Always power down before installation or maintenance, and follow standard electrical safety practices. Use in environments and with liquids that are appropriate for wet/humid locations as indicated by the product description.

For mid-range sensing needs, compare with Sundex 2 m Float Switch for shorter ranges and Sundex 5 m Float Switch for longer ranges. The 3 m model sits between these options in sensing distance and is ideal when your tank requires a mid-range solution.

Yes. It combines a compact design, durable and corrosion‑resistant float material, a 3 m sensing range, and an adjustable setup, delivering reliable liquid level control with low maintenance—making it a cost‑effective solution for many domestic and commercial applications.

Yes. The product description notes suitability for wet and humid locations, and its corrosion‑resistant float material is designed to withstand such conditions when used with compatible liquids.

Common issues include restricted float movement due to debris, loose or damaged wiring, or incorrect adjustment causing the float to miss level points. To troubleshoot: power down, inspect for obstructions, clean the float and housing, verify proper adjustment range, and ensure all electrical connections are secure before retesting with tank level changes.
