4.15 How to use the Frequency Output
There is a Frequency Output in all the series flow meters. This frequency output signal,
which represents the flow rate, is intended to connect with other instruments.
The Frequency Output is totally user-configurable. Generally, four parameters should be
configured for the setups.
Enter the lower flow rate value in window M68 and the higher flow rate value in window
M69.
Enter the frequency range in window M67.
For example, assume that the flow rate varies in a range 0m
3
/h to 3000m
3
/h, and an output
signal is at a maximum frequency of 1000Hz, the minimum of 200Hz is going to be required
for other instrumentation. The user should enter 0 in M68 and 3000 in M69, and enter 200
and 1000 in window M67.
Please note that the user has to make the selection with OCT setups in window M78.
4.16 How to use the Totalizer Pulse Output
The totalizer output will produce a pulse output with every unit flow of the totalizer.
The totalizer pulse output can only be realized by mapping the pulse output to the OCT or
BUZZER hardware devices.
For example, assume that the POS totalizer pulse output is needed, and every pulse
should represent 0.1cubic meter of liquid flow; the pulse output will be mapped to the
internal Buzzer, so that with every 0.1 cubic meter of flow the BUZZER will beep for a while.
The following setups should be taken / performed:
Select the unit Cubic Meter under window M32.
Select the Multiplier as ‘2. X0.1’ under window M33.
Select the output option ‘9. POS INT Pulse’ under window M77. (INT stands for totalized )
