Device for regulating flow of liquid through fluid conduit with small cross section, has adjuster in conduit to affect flow, flow sensor in conduit to detect actual flow value and regulator.

摘要

A regulator (5) delivers an adjusting signal for an adjuster by relying on flow actual and set point/target values. To minimize the effect from gas pockets (6) on flow control in a liquid, a monitoring device (7) detects a gas pocket in a fluid conduit (1) and controls a changeover device (4). As the gas pocket travels past a flow sensor (3), the changeover device delivers a replacement signal (x') to the regulator instead of the actual flow value (x) supplied by the sensor.
