Collection:Bürkert SE30 basic paddle wheel flow meter electronics (requires S030 fitting)

The Bürkert SE30 is the basic transmitter for an inline paddle wheel flow meter. It fits onto an S030 fitting, picks up the spinning paddle wheel, and sends a pulse signal whose frequency tracks the flow rate. It has no display and no switch output, so it suits a setup where another device, such as a PLC or counter, takes the pulse and does the rest. Combine it with an S030 fitting for a complete flow meter.

When to choose the SE30

Pick the SE30 when only a flow pulse is needed and the reading is shown or totaled elsewhere. For an on-device display, a switch contact, or a 4 to 20 mA signal, step up to the SE32 or SE35. The SE30 runs on a low-voltage DC supply and connects through a DIN form A plug.

Frequently asked questions

What does the SE30 connect to?

The pulse output feeds a counter, a PLC input, or a Bürkert controller, which turns the frequency into a flow rate and a running total. Without one of those there is no local reading, because the SE30 has no display of its own.

Which fitting does the SE30 mount on?

An S030 inline fitting, which holds the paddle wheel the SE30 picks up. The same SE30 also fits the S077 oval-gear fitting, so it can be reused if the line later switches to oval-gear measurement. Order the SE30 with whichever fitting suits the pipe and liquid.
