Sewage Pumping Station Radar Level: A Published Case and RFQ Review

The published case and its owner

KROHNE describes a wastewater pumping station operated by an unnamed municipal authority in South-East Queensland, Australia. Its wet well experienced rapid level changes. The existing submerged pressure probe was reported to respond too slowly and to need attention because of clogging. The manufacturer describes a trial and installation of its non-contact OPTIWAVE 1540 radar above the pit.

This is KROHNE's published application, linked under sources. It is not a WESIVO customer project, and it does not establish that all pressure probes are unsuitable. No customer identity, savings, flood-prevention result or comparative performance is independently claimed here.

Turn a process problem into a reviewable requirement

For a separate project, write down what the receiving system must detect and when. Record normal low and high levels, the expected fastest rise and fall, and the controller's existing start/stop logic. Agree the measurement update and response information to request; a catalogue accuracy figure alone does not describe the complete channel's timing.

Keep the measurement review separate from approval of pump control and high-level protection. The responsible plant team must define those functions and their acceptance criteria.

Separate the measurement path from flood exposure

Provide a pit elevation, mounting reference, inlet location, ladders and pump equipment. Mark the normal highest liquid level and any exceptional level that could reach the sensor, cable entry or connection box. Include access photographs taken under the site's approved procedures.

Request the exact ordered assembly's environmental and installation documentation. A protection rating or immersion statement for the device in the KROHNE example cannot be transferred to another radar, cable connection or WESIVO configuration.

Agree a handover record before ordering

• Identify whether each displayed value is distance, level or volume, with its unit and reference point.
• Record the sensor output, power supply, PLC input and configured range at both ends.
• State how invalid or stale readings will be represented to the receiving system.
• Define which accessible reference conditions, records and authorised checks will support acceptance.
• Keep the selected model, configuration revision and mounting drawing with the quotation.

These are preparation items, not instructions to change live pump settings or enter a wet well. For an unstable reading, the linked echo-diagnostic guide explains what evidence to collect before asking for a setting change.

Prepare a WESIVO enquiry

The related RD08A page and original WESIVO level catalogue are starting points for a configuration discussion. Send the medium, level range, mounting drawing, surface condition, temperature, pressure, flood exposure, required signal, quantity and delivery country through the product enquiry or contact page.

Ask for written confirmation of the selected configuration's suitability, available diagnostics and documentation. This article does not assign the external case's enclosure rating, response performance, software, hazardous-area approval or pump-control capability to a WESIVO product.
