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.
