Why choose· 01

Built for your duty.

Self-cleaning antenna path

A purge port allows clean dry air to help keep the antenna or lens surface clear in heavy dust.

Built for silo dust

This configuration is commonly requested for fly ash, cement, mineral powder and pellet silos.

RFQ needs air details

Air pressure, air quality, operating dust level and whether purge runs continuously or intermittently should be confirmed.

Engineer-checked selection

WELK checks medium, tank/silo height, nozzle drawing, measuring range, pressure, temperature, output signal and certificate 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.

Air-purge radar is a high-frequency radar level meter configuration for solids or sticky vapors where dust or buildup may cover the antenna surface.

This self-cleaning radar option is handled as project-reviewed configuration; WELK quotes it as a configured radar package with purge connection, antenna selection and installation notes confirmed by project.

80 GHz Radar Level Meter with Air Purge 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.

Radar selection starts from medium dielectric, measuring distance, nozzle size, vapor/foam/dust condition, pressure, temperature and whether the antenna needs purge, aiming or hazardous-area approval.

Air purge is useful when dust or condensation can coat the antenna; purge air must be clean, dry and compatible with site practice.

FAQ· 06

80 GHz Radar Level Meter with Air Purge questions.

How do I select 80 GHz Radar Level Meter with Air Purge?

Start from medium, tank/silo height, nozzle drawing, measuring range, pressure, temperature, output signal and certificate requirement. WELK then confirms the exact model, material and output before quotation.

What is the difference between 80 GHz Radar Level Meter with Air Purge and ultrasonic?

80 GHz Radar Level Meter with Air Purge is selected for its specific duty and limitations. WELK compares it with ultrasonic, hydrostatic, guided wave radar when the process data suggests another technology may be safer.

Can 80 GHz Radar Level Meter with Air Purge 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 80 GHz Radar Level Meter with Air Purge?

Air purge is useful when dust or condensation can coat the antenna; purge air must be clean, dry and compatible with site practice.

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.
