Ignition Modules Extract EFM Data with MQTT to Share Value Across the Enterprise
Cirrus Link announced the availability of Electronic Flow Measurement (EFM) Modules for the Ignition platform by Inductive Automation; including the EFM Emerson ROC Module, EFM Export Module, and MQTT Recorder Module. EFM data gathered with proprietary protocols is difficult to share across the enterprise, but Cirrus Link allows customers to extract and normalize EFM data with the efficient, open standard MQTT protocol.
Cirrus Link EFM Modules provide the following benefits:
- Retrieve SCADA and Record data faster and with less bandwidth
- Store and forward data at the Edge
- Connect EFM data to Flow-Cal transaction queues and/or an SQL database
- Collect guaranteed records and time-stamp data at the source
- Set up alarms, configurations, and history records and create tables in Ignition

“EFM is the cash register for the oil and gas industry, measuring hydrocarbons to calculate production and revenue,” said Arlen Nipper, President and CTO, Cirrus Link. “Industry flow devices gather EFM data but represent it differently in their proprietary protocols making extracting and sharing the data through the enterprise a challenge. We developed a range of EFM models to extract the data with MQTT to solve this problem.”
The EFM Emerson ROC Module is a protocol driver for the Ignition OPC UA module, polling EFM data and making it available as tags within the OPC browser. Custom configurations can be created and quickly scaled across hundreds of deployed devices.

The EFM Export Module receives EFM information from flow computers via MQTT including alarms, events, configuration and QTR records. This data is passed and put in the proper format and placed into transaction queues for Flow-Cal.
The MQTT Recorder Module uses MQTT to take the flow computer data in PLCs and RTUs and publish it as an immutable record that automatically populates a table within a database.
“What Cirrus Link is doing differently is instead of using legacy protocols that trap valuable EFM data, they are using MQTT as a new standard that is more efficient and makes the data available to more applications,” said Jerod Blocker, Operational Technology Manager, ARB Midstream. “Their modules are innovative and this development is key for the oil and gas industry as companies work to adopt IIoT.”
