Why choose· 01

Built for your duty.

Hazardous-area planning

Explosion-proof or intrinsically safe versions are selected only after the required certificate and area classification are known.

Non-contact design

Radar keeps the sensing element out of the liquid, reducing wetted-part exposure in aggressive or volatile media.

Signal compatibility

Analog, digital and relay-display systems can be planned around the plant's control architecture.

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.

Explosion-proof radar level transmitters are used for tank farms, solvent storage, petrochemical vessels and other applications where hazardous-area compliance matters.

WELK asks for the area classification, medium, process temperature, pressure, tank height, output signal and required certificate before quotation.

Explosion-Proof 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

Explosion-Proof Radar Level Transmitter questions.

How do I select Explosion-Proof 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 Explosion-Proof Radar Level Transmitter and ultrasonic?

Explosion-Proof 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 Explosion-Proof 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 Explosion-Proof 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.
