Yes, at Cooper we have a flow requirements for sampling. Our samplers have a bypass side and the sample side. The combined flow is high enough to ensure we have ~ 6 linear feet per sec flow in the line that feeds to sampler to keep corrosion products suspended. This can also be described as keeping the Reynolds Number high enough to provide turbulent flow (This information was provided from our Plant Chemist).

Do you know them and are you expecting this? - Look again! Use the "Report Phishing" button if you think this is a phishing email. Phishing is the #1 threat to NPPD. You are our best defense!! Stay Vigilant! ________________________________ I know this is a chemistry question.. maybe you could forward for me to someone in Secondary Chemistry at your site??? Recommendations for the "correct" Listserver to post this to will work as well!! At Robinson we have these samplers performing continuous sampling of Feedwater and Heater Drains. Question is - Does your site have both a Pressure Requirement (> 50 psi) and a Flow Requirement (≥ 100 mL/min through sample line) for corrosion product sampling with this instrument???
