Why choose· 01

Built for your duty.

Simple switching

A magnetic float actuates a reed switch at the set level point.

Low-cost alarm duty

Good for clean liquid tanks where continuous level is not needed.

Custom stem or cable

Mounting length, float material and switch logic can be configured by tank layout.

Engineer-checked selection

WELK checks medium, alarm height, mounting orientation, connection, output logic, power, contact rating and material requirement so the quoted configuration matches the application.

Application-matched configuration

Selection notes focus on real tank conditions, measuring range, process connection, output signal and installation limits.

Product details· 02

How it is selected & specified.

Magnetic float switches are mechanical point-level devices for high alarm, low alarm, pump start/stop or dry-run protection.

They are best used with clean liquids where the float can move freely without heavy buildup, viscosity or solids.

Magnetic Float Level Switch is presented as a configurable WELK product family. Final model limits, wetted materials, process connection, certificate and output signal are confirmed from the selected datasheet before quotation.

Point level switch selection starts from medium behavior, alarm point, mounting direction, density or dielectric, buildup risk, process connection, power and contact logic.

FAQ· 06

Magnetic Float Level Switch questions.

How do I choose the switching point for Magnetic Float Level Switch?

Start from medium, alarm height, mounting orientation, connection, output logic, power, contact rating and material requirement. WELK then confirms the exact model, material and output before quotation.

What is the difference between Magnetic Float Level Switch and continuous transmitter?

Magnetic Float Level Switch is selected for its specific duty and limitations. WELK compares it with continuous transmitter, radar, ultrasonic when the process data suggests another technology may be safer.

Can Magnetic Float Level Switch be customized?

Yes. Range, process connection, wetted material, output signal, cable length, display, switch points, documents and OEM label can be reviewed by product family.

What are the common limits of Magnetic Float Level Switch?

Sticky buildup, coating, turbulence, low density solids, non-conductive liquids or tank-wall material can make one switch principle unsuitable.

Are the listed specifications final for every project?

No. Published values are typical selection ranges. WELK confirms final limits, material, output, certificate and documents from the actual process data before quotation.
