5. DescriPTion
5.1. intended application area
The flow transmitter / pulse divider Type 8022 is designed
for use in industrial environments, in particular for the area of
control technology.

5.2. General description

The device type 8022 is an electronic module that, when it
is combined with a flow sensor, converts into a flow rate the
fluid velocity measured by the sensor.
The electronic module may be fitted with a display and
configuration unit.
The electronic module may operate as a flow transmitter
thanks to a 4-20 mA current output, or as a pulse divider.
By default, it operates as a flow transmitter. The display and
configuration unit makes it possible to change the operating
mode into pulse divider.
5.3. combined sensor
• The flow transmitter type 8022 must be combined to a
Bürkert flow sensor of the following types: 8020 Low
Power, 8030 Low Power or 8070 Low Power.
• The pulse divider type 8022 can be combined to a flow
sensor type 8020 with a pulse output, 8030 with a pulse
output or 8070 with a pulse output.

5.4. functions

note
The device is not tight when the display and configu-
ration unit is removed.
• Screw the cover with order code 670549 on the
device as soon as the display and configuration unit is
removed.
The display and configuration unit is only required
to indicate the flow rate or to configure the device
type 8022. It can be removed after the settings
have been made.
• When operating as a flow transmitter, the 8022 converts
the frequency signal generated by the combined Bürkert
flow sensor into an analogue 4-20 mA current signal
(2-wire connection).
• When operating as a pulse divider, the 8022 converts
the frequency signal generated by the combined Bürkert
flow sensor into an adjustable frequency signal (3-wire
connection).
