Chapter 1 What is the Configurable Flowmeter Module?
• Status indicators - Indicators display the status of communication,
module health and input/output devices. Use these indicators to help in
troubleshooting.
• Top and bottom guides - Guides provide assistance in seating the RTB or
IFM cable onto the module.
Typical Applications
You can use the 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 module in a turbine shaft speed-monitoring application.
In this example, the module is operating in High Resolution Frequency mode.
Other examples are shown in
Chapter 3 to reflect the various operational
modes available on the module.
For a detailed explanation of how the module works with other portions of a
ControlLogix control system, see
