4-20 mA Output
4-20 mA output
- this parameter is used to select the value that will be presented on the 4 - 20
mA output. When velocity is selected the output current will be proportional to the measured
velocity. When none is selected 4 - 20 mA output will be disabled.

4-20 mA min.
– To configure the 4-20 mA output range, the minimum measured value which will
correspond to 4 mA analog output needs to be set. The value is set in the currently configured
measurement unit. Example: if values measured by the instrument are expected to be within
the range of 700 mm/s to 1500 mm/s, it is recommended to configure the minimum value to
slightly below 700 mm/s (for example 500 mm/s). Alternatively, if the resolution is not critical, then
minimum value for 4-20 mA output can be left to the instrument minimum of 0 mm/s.
4-20 mA max.
– To configure the 4-20 mA output range, the maximum measured value which will
correspond to 20 mA analog output needs to be set. The value is set in the currently configured
measurement unit. Example: if values measured by the instrument are expected to be within the
range of 700 mm/s to 1500 mm/s, it is recommended to configure the maximum value to slightly
above 1500 mm/s (for example 2000 mm/s). Alternatively, if the resolution is not critical, then
minimum value for 4-20 mA output can be left to the instrument maximum of 15000 mm/s.
Processing Parameters
Sensitivity Level
Sensitivity level
– Configures the radar sensitivity level. The sensitivity level threshold is used by the
radar to determine whether the reflected signal is too low to detect any flow. If the instrument is
incorrectly reporting flow when there is no water in the channel, it’s necessary to increase the value
of this parameter.
