Type 8719 is an instrument for liquid flow control in process technology. Typical applications include liquid dosing in heat treatment, machine tools, fuel cell technology processes.

Features

  • High dynamic control through fast flow measurement
  • Applicable for liquid dosing up to 600 ml/min (36 l/h)
  • No moving parts in medium
  • Protection class IP65
  • Fieldbus optional

A proportional valve working at low friction ensures high sensitivity and good control.

The measured value provided by the sensor is compared with a predefined set point. 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 changes or other disturbances in the system.
