data to be stored in the logger buffer.
Logging data can be redirected to the RS-232C interface without being stored into
the logger buffer.
Use M53 to view the data in the logger buffer.
Dumping the logging data through the RS-232C interface and the clearing of the
buffer can be operated with a function in window M52.
6.15.How to use the Frequency Output
There is a Frequency Output in all 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 0m3/h to 3000m3/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 by selecting the 13th option reading like ‘FO output’ to direct the frequency
output to the OCT OUTPUT hardware device.
6.16.How to use the Totalizer Pulse Output
The totalizer output will produce a pulse output with every unit flow of the totalizer.
Refer 3.4 and 3.5 for the setups of the totalizer units and multiplier.
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:
