SENTRY CPS Corrosion Product Sampler

CPS is used for sampling corrosion products (particulate and dissolved metals such as iron and copper) carried in the steam-water cycle. With it, the operator can investigate the cause of corrosion, monitor its development and assess whether the applied corrosion prevention program is working. The system includes high-pressure filters and a digital flow meter that stays accurate at low flow; cation and anion filters are used together to separate corrosive substances.

• Complies with ASTM D6301.
• Wetted parts are 316 stainless steel, PTFE and Viton.
• Standard pressure up to 197 bar; sample temperature up to 55 °C without a cooler and up to 538 °C with a cooler.
• Flow up to 500 cc/min.

You can choose between a standard fixed panel and a small portable battery-powered panel; power can come from a three-month battery or a 100-240 VAC connection. A fast line, sample cooling and pressure reduction are offered as additional modules.

Keeping flow constant during sampling is important, because the amount of corrosion product accumulating on the filter is interpreted together with flow and time. The digital flow meter is therefore chosen to give reliable readings even at low flows.

Tetra determines the CPS configuration suited to pressure and temperature conditions, and provides on-site support for planning sampling campaigns and filter change procedures. Supply of consumables such as filters and sealing elements is also handled locally.
