  • Description
  • Specification
  • Downloads
The Burkert type 8026 insertion flowmeter is a compact device, specially designed for measuring the flow rate in solid-free liquids, in a variety of applications (water, waste water monitoring, chemical processing, etc.). Type 8026 is available with:
  • 2 configurable outputs: one transistor output (NPN) and one 4…20 mA current output (2-wire)
  • 3 configurable outputs: two transistor outputs (NPN/PNP) and one 4…20 mA current output (2-wire)
  • 4 configurable outputs: two transistor outputs (NPN/PNP) and two 4…20 mA current outputs (3-wire).
Type 8026 converts the measured signal, displays different values in different units (if display/configuration module mounted) and computes the output signals, which are provided via one or two M12 fixed connectors. Thanks to 1 or 2 transistor outputs, the flowmeter can be used to switch a solenoid valve, activate an alarm and, thanks to 1 or 2 current outputs, establish one or two control loops.

Featuring:

  • Up to PN10, size of measurement pipes: DN 20…DN 400
  • Configurable outputs: one or two transistor output(s) and one or two 4…20 mA current output(s)
  • Removable backlit display/configuration module for indication of flow rate and volume with two flow totalizers
  • Automatic calibration using Teach-In, all outputs can be checked without the need for actual flow
