Flow computer IA DigiFlow 515

Applications:

Flow computer IA DigiFlow 515 combines compensation for gas and vapors to the following equations. Ideal Gas: Temperature and pressure correction; compressibility correction not required. General Gas: Temperature and pressure correction with compressibility correction calculated using the Redlich-Kwong state equation. This equation is suitable for gases with known properties. Information about common industrial gases are provided in the operating manual. Natural Gas: Compressibility is calculated using the AGA-NX-19-mod equation for natural gases of low gross caloric value. Steam Flow Computer: Based on the IFC 1967. Mass flow correction of the flowing steam using pressure and temperature. Energy: The heat quantity is calculated based on enthalpy and mass flow.(for steam) Energy Balance: Assuming a mass balance in upstream-and downstream pipe, an energy balance of the loop is calculated. (for steam in upstream)
