There is a Frequency Output in all TUF-2000 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 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.
