Setting The Flow Rate Range Associated To The 4-20 Ma Output; Choosing The Filter Of The Flow Rate - Burkert 8032 Manuel D'utilisation

9.5.4. setting the flow rate range
associated to the 4-20 mA output
The 4-20 mA output provides an electrical current, the value of
which reflects the flow rate measured by the device.
• The signal may be inverted, i.e. the flow rate value associated to the
20-mA current is lower than the one associated to the 4-mA current.
• The current output gives a 22-mA current when the device shows
an operating error.

choosing the filter of the flow rate

To function "BRGR"
The "Filter" function is used to attenuate the display and 4-20 mA
output, if any, fluctuations when the flow rate varies in the process.
Ten attenuation levels, from 0 (means no attenuation) to 9 (maximum
attenuation of the fluctuations) are available.
