Collection:Bürkert 8041 basic insertion electromagnetic flow meters

The Bürkert 8041 is a basic insertion electromagnetic flow meter for conductive liquids. The probe is fitted into the pipe through a mounting fitting, and electrodes pick up the voltage the moving liquid creates. With no moving parts in the flow, it measures dirty and particle-laden liquids that would foul a paddle wheel, as long as the liquid conducts electricity. It has no display and reports through its output signals, which suits a meter read from a control panel.

When to choose the 8041

Pick the 8041 where a local display is not needed and the signal is sent to a PLC or control system. It gives a 4 to 20 mA signal, a frequency (pulse) output, and a relay contact together. Match the wetted parts to the liquid: the sensor body is stainless steel or PVDF, and the electrodes stainless steel or, for more aggressive liquids, Alloy C22. For a built-in display, choose the 8045.

Frequently asked questions

Does the 8041 show a reading at the pipe?

No. The 8041 has no display and reports only through its 4 to 20 mA, frequency (pulse), and relay outputs. A control system or panel meter shows the value. For a reading at the meter itself, the 8045 adds a display.

Which wetted material for an aggressive liquid?

The sensor body is stainless steel for general water-based liquids, and PVDF for more corrosive media. The electrodes are stainless steel, or Alloy C22 where the liquid attacks stainless. Match both to the liquid, since they are in constant contact with it.
