New Alternatives to Online DPD Instruments for TRO Measurement in BWMS

The DPI Amperometric is a new alternative to Online DPD Instruments. When used in Ballast Water
Management Systems (BWMS), this alternative eliminates some potential compliance issues. Unique features
include:
• Direct measurement of TRO in ballast pipe for faster response (<45 seconds).
• Robust and accurate operation in muddy ports.
• Accurate operation at 6 times the DOC (Dissolved Organic Carbon) challenge levels that BWMS are
tested to.
• Flow Independent- Accurate operation while experiencing ballast flow changes.
• Models available for Hazardous and Non-Hazardous, Open Deck, Side Stream, and Ballast Pipe
installation.
• The sensor works reliably at 20 times the TSS (Total Suspended Solids) levels, or greater, required by ETV
(1000 ppm) without any filters.
• Integrated salinity measurement eliminates the cost of a discrete salinity sensor.
• Integrated pH sensor can withstand 10 bar and -0.7 bar and is stored dry.
