Why choose· 01

Built for your duty.

Small installation footprint

Compact housings fit tanks, channels and pump stations where access space is limited.

Radar stability

Radar is not affected by air temperature in the same way as acoustic ultrasonic measurement.

Simple commissioning

Loop-powered or digital-output versions can be matched to common PLC and display systems.

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.

Compact radar transmitters are normally selected for clean liquid, wastewater and utility tanks where a non-contact instrument is desired but a long-range silo radar is unnecessary.

WELK checks the dead zone, tank height, beam path, mounting thread, enclosure rating and signal protocol before confirming the final model.

Compact Radar Level Transmitter 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.

FAQ· 06

Compact Radar Level Transmitter questions.

How do I select Compact Radar Level Transmitter?

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 Compact Radar Level Transmitter and ultrasonic?

Compact Radar Level Transmitter 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 Compact Radar Level Transmitter 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 Compact Radar Level Transmitter?

Very low dielectric media, heavy buildup on the antenna, severe internal obstructions or unusual nozzle geometry should be reviewed before order.

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.
