Why choose· 01

Built for your duty.

Short-tank fit

A small blind zone helps when the tank is shallow and the maximum level is close to the mounting point.

Compact cost control

This sub-series is useful for OEM equipment and water tanks where a full transmitter is unnecessary.

Clear mounting rule

The highest liquid level must still stay below the sensor's blind-zone limit.

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.

Low blind-zone ultrasonic sensors are selected for small vessels, dosing tanks and compact water systems.

WELK confirms maximum fill level, tank height, beam clearance and whether the buyer needs analog, switch or RS-485 output.

Low Blind Zone Ultrasonic Level Sensor 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

Low Blind Zone Ultrasonic Level Sensor questions.

How do I select Low Blind Zone Ultrasonic Level Sensor?

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 Low Blind Zone Ultrasonic Level Sensor and radar?

Low Blind Zone Ultrasonic Level Sensor 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 Low Blind Zone Ultrasonic Level Sensor 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 Low Blind Zone Ultrasonic Level Sensor?

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.
