7.2.2. Frequency Output
It is mainly used for manufacturer coefficient calibration and user measurement use.
In the third group configuration parameters setting: frequency corresponds to
real-time flow rate, upper frequency limit corresponds to max. flow rate.
Note: maximum frequency is set to 5000 Hz.
7.2.3. Current Output
Mainly used for transmitting output to other intelligent instruments, such as: digital
display table, recorder, PLC, DCS, etc.
The current output type: 4 - 20mA.
The current valve corresponds to real-time flow rate, 20mA corresponds to range
limit, 4 mA corresponds to range limit.
