# Flow meters and maintenance for the wastewater network

Hoogheemraadschap van Rijnland is procuring flow meters and components, installation and commissioning, and annual maintenance across its wastewater network. The notice covers replacement and new meters, including electromagnetic and Coriolis meters, air-flow meters and level measurement used to determine flow. Contractors must install, calibrate, test and document meters; inspect new equipment at commissioning; maintain and inspect existing equipment on a risk-based schedule; dry-calibrate all critical meters annually; and advise on deviations between meters in series. The current system has about 380 meters, with around 20 non-critical meters expected to need annual on-request dry calibration. The contract runs for 48 months; Die TED-Bekanntmachung vergibt 60 Punkte für Qualität, darunter proaktive und risikogesteuerte Wartung, und 40 Punkte für den Angebotspreis. The cutoff is 16 November 2026 at 11:00 CET (UTC+01:00).
