Why choose· 01

Built for your duty.

No moving float

A vibrating fork detects covered/uncovered condition without relying on a mechanical float.

Reliable liquid alarm

Suitable for many liquids even with turbulence, bubbles or moderate coating risk after review.

Control-panel friendly

Relay, transistor or NAMUR-style outputs can be matched to safety or PLC inputs by model.

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.

Tuning fork switches are point-level instruments used for high alarm, low alarm, pump protection and overflow prevention in liquid tanks and pipes.

Selection depends on density, viscosity, buildup risk, process pressure, temperature and required output.

Tuning Fork Level Switch for Liquids 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

Tuning Fork Level Switch for Liquids questions.

How do I choose the switching point for Tuning Fork Level Switch for Liquids?

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 Tuning Fork Level Switch for Liquids and continuous transmitter?

Tuning Fork Level Switch for Liquids 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 Tuning Fork Level Switch for Liquids 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 Tuning Fork Level Switch for Liquids?

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.
