Setup procedure for the de-bubbler
For systems that include a de-bubbler, refer to Figure 6:
1 Open the 'sample in' isolating valve
2 Adjust the sample flow through the turbidity system with the flow regulating valve
Note
It is recommended to use the sample regulating valves together with a flow indicator to ensure easy maintenance and consistent
performance. These devices are not supplied with the 4690 Turbidity systems.
