4-20 mA
In the 4-20 mA output type, output flow-rate data is indicated by electric current.
This type is commonly used when Octave flow-rate measurements serve as
input for pump controllers. The pump controller matches the flow-rate values to
the pump’s set points to ensure the pump engine is working efficiently. The
pump controller prevents a situation in which the measurements will deviate
from the allowed range set in Octave. Per the measured input from Octave it
instructs the pump to either accelerate or slow down its pace to work within the
range of the optimal set points (minimum and maximum limits).
When using this output type, you will set the minimum and maximum flow rate
limits that correspond to the standard range 4 mA minimum to 20 mA maximum
respectively.
Measurement units are based on the units set for the meter’s Display.
Minimum – set the minimal flow rate for the 4 mA set point.
Maximum – set the maximal flow rate for the 20 mA set point.
