Where should a dissolved-oxygen sensor be installed in a pond?

A dissolved-oxygen probe only represents the pond if it sits in the right place. Placement, mounting, cable protection and bus addressing are decided before commissioning.

Keep the probe at least 3 m from an aerator and away from feeding zones, use one monitoring point per pond plus zone points on large ponds, choose a float, fixed or buoy bracket, and protect the underwater and bank cable runs.

What are the placement and installation rules?

These rules come from the sensor installation guide and the field troubleshooting handbook; they are the checks used before a pond is handed over.

RuleWhy / what to look forWhat to do
Keep clear of aerator turbulenceBubbles on the probe distort the readingInstall at least 3 m from the aerator
Avoid feeding zonesFeed and waste disturb the local oxygen readingChoose a representative point away from feeding

Frequently asked questions

Do I need to register or leave an email to use these guides?

No. All troubleshooting and commissioning guides on this site are open pages with no form and no email gate. The full product datasheets are also open on the downloads page.

Do these pages publish spare-part prices or service fees?

No. These pages publish technical checks, wiring rules and procedures only. For spare parts, service terms or a quotation, contact [email protected].

Which mounting method is recommended?

The float bracket is the recommended option in the installation guide; a fixed bracket or buoy is used where pond depth or bank structure requires it.

Do I need one probe per pond?

At least one monitoring point per pond, with additional zone points by aerator group on large ponds. Check placement against pond shape and depth.
