Why choose· 01

Built for your duty.

Hazardous-area option

Explosion-proof selection requires area classification, gas group and temperature class before quotation.

Economical non-contact choice

Where vapor and foam are manageable, ultrasonic can be a lower-cost alternative to radar.

Remote controller option

Split display/controller versions can keep electronics away from harsh tank-top access points.

Engineer-checked selection

WELK checks tank height, maximum level, blind-zone allowance, medium, vapor/foam condition, output signal, power and relay points 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 ultrasonic meters are not a universal replacement for radar; they are suitable only when acoustic measurement conditions remain stable.

WELK reviews vapor, foam, turbulence, chemical compatibility and required certificate before recommending this product.

Explosion-Proof Ultrasonic Level Meter 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.

Ultrasonic selection depends on blind zone, tank height, vapor, foam, turbulence, temperature gradient and whether a split display, relay output or corrosion-resistant sensor face is needed.

FAQ· 06

Explosion-Proof Ultrasonic Level Meter questions.

How do I select Explosion-Proof Ultrasonic Level Meter?

Start from tank height, maximum level, blind-zone allowance, medium, vapor/foam condition, output signal, power and relay points. WELK then confirms the exact model, material and output before quotation.

What is the difference between Explosion-Proof Ultrasonic Level Meter and radar?

Explosion-Proof Ultrasonic Level Meter is selected for its specific duty and limitations. WELK compares it with radar, hydrostatic, float switch when the process data suggests another technology may be safer.

Can Explosion-Proof Ultrasonic Level Meter 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 Ultrasonic Level Meter?

Heavy vapor, pressure variation, dense foam, strong turbulence or narrow nozzles can weaken the echo; radar may be safer in those conditions.

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.
