8072 Positive Displacement Flowmeter

Brand: Burkert Fluid Control Systems
Does not ship to Virginia, United States

This positive displacement flowmeter/threshold detector with display is designed for use in slighly viscous fluid like glue, honey or oil and specially to switch a valve and to establish a monitoring system or an On/Off control loop. The switching points can be configured with the 3-keys below the display.

The 8072 is available with On/Off output, or with process value outputs.
Features
  • Indication, monitoring, transmitting and On/Off control in one device
  • Selectable outputs (transistor or relay)
  • Automatic calibration: Teach-In
