Lambda Tuning the Universal Method for ... - Control Global
The arrest time or Lambda is the time for the PV to reach maximum deviation and begin returning to SP. After reaching steady state, there will be no oscillation. We chose Lambda = 240 to keep the level PV away from the alarm limits for large disturbances. For applications where tight level control is needed, a smaller Lambda value can be chosen.

www.controlglobal.comAs pressure changes occur within a throttling valve, it is possible to produce 2-phase flow at the valve’s outlet for either a liquid or gas-vapor at the inlet. A “vapor” is a “gas” that is at, or relatively near, its “saturation” (boiling) conditions of pressure
