Why choose· 01

Built for your duty.

Simple conductive detection

The liquid completes an electrical path between electrodes or to the tank wall.

Multi-point control

Multiple electrodes can support pump start, stop and alarm points.

Cost-effective water duty

Best suited for conductive water-like media where coating, foam and oil layers are not dominant.

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.

Conductive level switches are simple point-level systems for water, wastewater and other conductive liquids.

They are not suitable for non-conductive oils or solvents and should be checked for coating, corrosion and electrode contamination.

Conductive 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.

Conductive switches only work with conductive liquids; they are not suitable for oil or non-conductive media.

FAQ· 06

Conductive Level Switch questions.

How do I choose the switching point for Conductive 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 Conductive Level Switch and continuous transmitter?

Conductive 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 Conductive 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 Conductive Level Switch?

Conductive switches only work with conductive liquids; they are not suitable for oil or non-conductive media.

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.
