Flowmeter with threshold detector for highly viscous mediums

8072 DN15-100 mm

• Indication, monitoring, transmitting and
On/Off control in one device
• Selectable outputs (transistor or relay)
• Automatic calibration: Teach-In

• Process value output: 4-20 mA

Complete sensor consisting of
Type SE32 and fitting Type S070

This positive displacement flowmeter/threshold detector with display Envelope Dimensions [mm] (see datasheet for details)
is designed for use in slightly viscous fluid like glue, honey or oil and
specially to switch a valve and to establish a monitoring system or an On/ DN H
Off control loop. The switching points can be configured with the 3-keys 15 85
below the display. The 8072 is available with On/Off output, or with H 25 100
4-20 mA process value outputs. 40 117
