Why choose· 01

Built for your duty.

Fits narrow access

Small-diameter probes are useful where standard submersible transmitters cannot pass through the well casing.

Deep well measurement

Range and cable length are selected from water column, static level and pump drawdown.

Simple telemetry signal

4-20 mA output can be connected to pump panels, data loggers or remote telemetry systems.

Engineer-checked selection

WELK checks liquid, density, measuring height, cable length or connection, temperature, pressure, output signal and material 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.

supplier catalog listings often separate 16 mm and 19 mm borehole sensors because probe diameter is a decisive purchasing filter.

WELK quotes this as a slim hydrostatic probe with diameter, cable length, range and cable material confirmed by the well drawing.

Small Diameter Borehole 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.

Pressure-based level selection starts from liquid density, range, cable length or process connection, diaphragm style, material compatibility, output signal and ventilation or remote-seal layout.

FAQ· 06

Small Diameter Borehole Level Transmitter questions.

How is the measuring range selected for Small Diameter Borehole Level Transmitter?

Start from liquid, density, measuring height, cable length or connection, temperature, pressure, output signal and material requirement. WELK then confirms the exact model, material and output before quotation.

What is the difference between Small Diameter Borehole Level Transmitter and radar?

Small Diameter Borehole Level Transmitter is selected for its specific duty and limitations. WELK compares it with radar, ultrasonic, magnetic gauge when the process data suggests another technology may be safer.

Can Small Diameter Borehole 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 Small Diameter Borehole Level Transmitter?

Density changes, coating, sediment, viscous media, vacuum, crystallization and blocked impulse lines can affect level calculation.

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.
