Liquid Flow

The Liquid Flow test allows you to check the flow of liquid through the sparger, reactor bypass, and through the
reactor. When you press the Liquid Flow button, the following screen appears:
Figure 68: The Liquid Flow Screen
When the Liquid Bypass Flow button is pressed, pump P1-R empties any liquid that may be in the sparger
through the reactor bypass in preparation for starting the test. Then, the syringe fills with dilution water, and the
dilution water is dispensed into the sparger. Valves V4-R, V5-R and V7-R are closed. Valves V3-R and V6-R are
opened, and pump P1-R empties the sparger through the reactor bypass. It takes a few seconds for the water to
exit the Liquid Waste tube on the rear of the Analyzer. If you do not see water exiting the waste tube while P1-R
is operating, or if the liquid level in the sparger does not go down, the reactor bypass may be plugged.
When the Liquid Reactor Flow button is pressed, pump P1-R empties any liquid that may be in the sparger
through the reactor bypass in preparation for starting the test. Then, the syringe fills with dilution water, and the
dilution water is dispensed into the sparger. Valve V6-R is closed, and valves V3-R, V4-R and V5-R are open.
Pump P1-R empties the sparger through the reactor tube. It takes a few seconds for the water to exit the Liquid
Waste tube on the rear of the Analyzer. If you do not see water exiting the waste tube while P1-R is operating, or
if the liquid level in the sparger does not go down, the reactor tube may be plugged. If the liquid level in the
sparger does not drop, it indicates that the tube is plugged.
