Why choose· 01

Built for your duty.

Small tank fit

The compact PP body is suited to utility tanks, small sumps and OEM equipment.

Multiple output choices

4-20 mA, voltage, RS-485 Modbus and NPN switch versions can be selected by control need.

Simple installation

A threaded mount and narrow sensor body simplify retrofit on small vessels.

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.

WKSL-100 is a compact ultrasonic sensor for short-range liquid measurement where a full display transmitter is not required.

It is best used where the medium surface is reasonably stable and the sensor has a clear vertical acoustic path.

WKSL-100 Compact 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.

Specifications· 03

WKSL-100 Compact Ultrasonic Level Sensor specification range.

Parameter	Value
Ranges	0.3-5 m / 0.3-8 m / 0.5-12 m
Resolution	1 mm
Beam angle	12 degrees
Supply	DC 12-24 V
Protection	IP65
Output	4-20 mA, voltage, RS-485 or NPN by model
Selection checks	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.
Common limitations	Heavy vapor, pressure variation, dense foam, strong turbulence or narrow nozzles can weaken the echo; radar may be safer in those conditions.
RFQ checklist	Send tank height, maximum level, blind-zone allowance, medium, vapor/foam condition, output signal, power and relay points.
Documentation	Manual, wiring note, calibration or inspection record can be requested with the order.

FAQ· 06

WKSL-100 Compact Ultrasonic Level Sensor questions.

How do I select WKSL-100 Compact 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 WKSL-100 Compact Ultrasonic Level Sensor and radar?

WKSL-100 Compact 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 WKSL-100 Compact 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 WKSL-100 Compact 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.
