The 2704 can be used solely to control Total Dissolved Solids (TDS), or also to control water level and boiler pressure. A specialist input module makes it compatible with standard TDS conductivity probes making both retrofit and new installations easy to accomplish. Additionally, Timed Bottom Blowdown and Steam Main Warm Up functions make use of the controller’s internal real time clock. For more detailed information on the 2704 as a boiler controller please refer to application note ANC169 on boiler types, and technical information note TIBC177 on TDS measurement.

6000 Flow Computer
The 6000 Flow Computers are ideal for energy and facility management. They can be used to monitor energy performance and to identify problems as they occur as well as for energy cost allocation.
-
Saturated steam calculations
-
Mass flow
-
Heat flow
-
Heat consumed
-
Easy to use touch screen technology
-
Up to 48 configurable input channels
-
Ethernet communications
-
Remote and mobile access
6000 series options have equations designed particularly for use with saturated steam. Mass Flow, Heat Flow and Heat Consumed can all be calculated and recorded. All of these equations can be set to use either pressure or temperature as the measured input and use look-ups from the 1999 ASME steam tables.
The 6000 Flow Computers are ideal for energy and facility management. They can be used to monitor energy performance and to identify problems as they occur as well as for energy cost allocation. Data can be presented and reported as required in Excel™ using Report software to access information from the secure process data files.
The 6000 Flow Computers have excellent communications capabilities allowing the units to be networked for data transfer to other systems or for remote access by the user, ensuring information is available wherever and whenever it is needed.
