Note: To manually measure the flow rate through the analyzer, measure the flow rate at the analyzer drain
when the analyzer flushes the cell with water.
2. For standpipe installations, turn the shut-off valve at the Y-strainer outlet to set the flow rate
between 60 and 200 mL/min when the analyzer flushes the cell with water.
3. For pressure regulator installations, adjust the pressure regulator to set the flow rate between
60 and 200 mL/min when the analyzer flushes the cell with water.
