Figure 15 illustrates a suggested hookup using a pressure regulator in the inlet
line and a flow meter or flow control valve on the outlet line. The control
valve is installed on the outlet side because it may introduce bubbles into the
sample causing positive interference in the turbidity reading. This hookup also
maintains sufficient pressure to minimize outgassing in a carbonated stream.
