Why choose· 01

Built for your duty.

Application-specific selection

closed tanks, pressurized vessels, remote-seal applications and process tanks where submersible probes or non-contact sensors are not suitable

Technical configuration window

Range class, output, materials and accessories are presented as configurable options so WELK can match the page to the real process data before quotation.

Configuration before quotation

Static pressure, density, zero elevation, capillary length, seal material, fill fluid, process temperature and mounting position are checked.

Limits kept visible

DP level is sensitive to installation geometry and density. It should not be quoted from tank height alone.

Product details· 02

How it is selected & specified.

Differential Pressure Level Transmitter for Tanks is presented as a WELK Level configurable product family, not as a single fixed catalogue code. The page focuses on realistic selection logic, installation limits and RFQ data that should be checked before quotation.

Closed tanks, pressurized vessels, remote-seal applications and process tanks where submersible probes or non-contact sensors are not suitable.

Static pressure, density, zero elevation, capillary length, seal material, fill fluid, process temperature and mounting position are checked.

DP level is sensitive to installation geometry and density. It should not be quoted from tank height alone.

FAQ· 06

Differential Pressure Level Transmitter for Tanks questions.

When is DP level better than hydrostatic probe?

Use DP when the tank is closed, pressurized or requires remote seals and a submerged cable probe is not suitable.

What data is required for sizing?

Send tank height, density, pressure, temperature, upper/lower connection positions and seal or capillary requirements.

What should I send for a quotation?

Send medium, measuring range, installation drawing or photo, process connection, output signal, power supply, environment and any certificate or document requirement.

Are final specifications fixed from this page?

No. Final range, accuracy, material, pressure, temperature, output and approval wording are confirmed from the selected order configuration.
