Type 8718 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 fixed value or a predefined profile can be followed, regardless of pressure

variations or other changes in the system. As a control element, a proportional

valve working at low friction guarantees ahigh sensitivity and the good

control characteristics of the unit.
