8072 Positive Displacement Flowmeter
Brand: Burkert Fluid Control Systems
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.
