Description
Many of today's flow meters offer multiple outputs which are assignable to flow and temperature. The ES761ST2 offers enhanced functionality to permit these multiple outputs to be used with added flexibility. This flexibility is utilized in common applications such as when computing the net energy of saturated steam energy in minus condensate return energy out. Flow and Temperature can be measured at the multi-variable flow meter. A separate temperature measurement can be made in the condensate. The ES761 then computes the mass flow of steam as well as the input energy of steam from the available input sensors on steam, will also compute, the energy in the condensate return, and will compute the net energy. Refer to diagram which follows. 

Addition Capabilities

• Increased uses for compensation input
• Increase variety of new flow meter types including verabar, accelebar, and mass flow meters.
• Increased variety of selections on:
• Display Scroll List
• Print List
• Current Outputs
• Relay Outputs
• RS232 Interface
• RS485 Interface

The ES761 preserves the core functionality offered by the Supertrol-2 family including the ES749 which can be summarized as follows:
The ES761ST2 Flow Computer satisfies the instrument requirements for a variety of flowmeter types in liquid, gas, steam and heat applications. Multiple flow equations are available in a single instrument with many advanced features.
