Flow Process Station (3502)
Coupling unions allow the Flow Process Station to be directly coupled with the Level Process Station, thereby creating flow control using a diaphragm-actuated control valve as the control element, or level control using the variable frequency pump drive. Coupling the two stations also provides for the two differential transmitters necessary to configure more advanced interactive control loops such as feed-forward or cascade control. A venturi element mounted in a 30-cm (12-inch) header assembly is included with the station.
