14 What is the Configurable Flowmeter Module?
Typical Applications
You can use the CFM module in power management, automotive, food and
beverage, and oil and gas industries for various flow and/or turbine metering
applications.
This figure shows a CFM module in a turbine shaft speed monitoring
application. In this example, the 1756-CFM module is operating in high
resolution frequency mode. Other examples are shown in Chapter 3 to reflect
the various operational modes available on the 1756-CFM module.
For a detailed explanation of how the CFM module works with other portions
of a ControlLogix control system, see Chapter 2, Configurable Flowmeter
Operation in the ControlLogix System.
