KEP meter ES761 Net Energy Flow Computer

KEP ES761 Net  Energy Flow ComputerNet Energy Flow Computer for Saturated Steam Energy & Condensate Return Energy

Many of today’s flow meters offer multiple outputs that 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.
