Collection:Bürkert 8025 insertion paddle wheel flow meters

The Bürkert 8025 is an all-in-one insertion paddle wheel flow meter for clean, low-viscosity liquids. Unlike the inline SE-plus-S030 meter, it is one unit: the paddle wheel is on a probe that is fitted into the pipe through a mounting fitting, with the display and electronics built in. It measures the flow on the spot and can send a 4 to 20 mA, pulse, or switch output. As a paddle wheel device it suits clean liquids with few solids: it works with up to about 1% solid particles no larger than 0.5 mm, but not heavily loaded or fibrous liquids.

Meter or batch controller

The compact 8025 is available as a flow meter or as a batch controller:

• Flow meter: measures and shows the flow, and sends it on as an output. A battery version shows and totals the flow with no output, for places without power.
• Batch controller: measures the flow and also doses a set amount. A target is set (for example 50 litres), the controller opens a valve, counts the flow, and closes the valve when the target is reached.

How it mounts

The 8025 probe is fitted into the pipe through a single port, so there is no full-bore meter body. A separate Bürkert S020 insertion fitting gives that port, in a connection and size to match the line. The meter and the S020 are ordered separately.

Frequently asked questions

What fitting does the 8025 need?

It needs a mounting point for the probe in the flow, such as an insertion fitting sized to the pipe. The 8025 has its own measuring element, so it needs no full-bore meter body, just the port the probe passes through.

How is the 8025 different from the SE plus S030 meter?

The 8025 is one insertion unit with a built-in display. The inline meter is two items ordered together, an S030 fitting and a separate SE transmitter, with the wheel in a full-bore body. The 8025 is quicker to fit on an existing pipe; the inline meter lets the transmitter be swapped without touching the line.

What is the difference between the compact 8025 and the remote transmitter?

The compact 8025 has the paddle-wheel probe and the electronics in one unit, so it measures on its own. The remote 8025 is a transmitter only: an electronics-and-display box with no sensor, listed under Transmitter electronics. A remote transmitter needs a separate flow sensor and that sensor's fitting to make a working meter.
