Liquid flow controller 8719

volumetricproportionalfor water

Type 8719 is an instrument for liquid flow control in process technology. The measured value provided by the sensor will be compared in the digital control electronics with the predefined set point according to the signal; if a control difference is present, the control value output to the proportional valve will be modified using a PI-control algorithm. In this way, the flow can be maintained at a fi xed value or a predefined profile can be followed, regardless of pressure changes or other disturbances in the system. As a control element, a proportional valve working at low friction guarantees the high sensitivity and good control characteristics of the unit. High dynamic control through fast flow measurement No moving parts in medium Protection class IP65 Fieldbus optional
