Why choose· 01

Built for your duty.

Application-specific selection

narrow tanks, bypass chambers, low-dielectric liquids, interface review and vessels where a guided probe gives a cleaner signal path

Technical configuration window

Range class, output, materials and accessories are presented as configurable options so WELK can match the page to the real process data before quotation.

Configuration before quotation

Probe type, length, dielectric, viscosity, buildup, agitation, nozzle, anchoring and interface contrast decide the configuration.

Limits kept visible

Guided wave radar is contact measurement. Sticky buildup, strong agitation, long cable tension and coating must be reviewed before order.

Product details· 02

How it is selected & specified.

Guided Wave Radar Level Transmitter is presented as a WELK Level configurable product family, not as a single fixed catalogue code. The page focuses on realistic selection logic, installation limits and RFQ data that should be checked before quotation.

FAQ· 06

Guided Wave Radar Level Transmitter questions.

When should I choose guided wave radar?

Choose it when a probe path is acceptable and free-space radar may see false echoes or interface information is required.

Can guided wave radar measure interface?

It can be reviewed when dielectric contrast is suitable and emulsion layers are not too thick.

What should I send for a quotation?

Send medium, measuring range, installation drawing or photo, process connection, output signal, power supply, environment and any certificate or document requirement.

Are final specifications fixed from this page?

No. Final range, accuracy, material, pressure, temperature, output and approval wording are confirmed from the selected order configuration.
