Flow Computer Verification Test Initiation for SCADA Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current SCADA systems lack the ability to directly interface with flow meters for initiating and monitoring verification tests, limiting the integration of diagnostic data into overall process systems and preventing remote interaction or archival of test results.
Innovation Solution
A flow computer system that communicates with a flow meter to initiate a verification test, retrieves diagnostic data, and logs results, enabling integration with SCADA systems for comprehensive system monitoring and data archival.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flow meters perform verification tests independently without SCADA integration, then operational simplicity is maintained, but system integration capability and remote monitoring capability deteriorate
Solution Approach 1:
The flow computer is designed to perform multiple functions: it serves as both a standard flow calculation device and a SCADA interface unit that can initiate, monitor, and archive verification tests. This multi-functionality allows the system to integrate diagnostic capabilities without requiring separate dedicated equipment, thus improving system integration capability while avoiding additional interface complexity.
Solution Approach 2:
The flow computer acts as an intermediary between the SCADA system and the flow meter. It receives initiation codes from the SCADA system, translates them into verification test commands for the flow meter, and then archives the results. This intermediary role enables SCADA integration without directly complicating the flow meter's internal architecture.
2Ease of operation
If verification tests are initiated locally at the flow meter, then operational simplicity is maintained, but remote monitoring capability and response time deteriorate
Solution Approach 1:
The flow computer continuously monitors for initiation codes from the SCADA system and is pre-configured to immediately translate and transmit these codes to the flow meter. This preliminary preparation ensures that when a remote initiation command is received, the verification test can start without delay, thus improving response time while maintaining ease of remote operation.
3Loss of information
If diagnostic data is not archived by the flow computer, then device complexity is reduced, but information availability and historical analysis capability deteriorate
Solution Approach 1:
The diagnostic data archival function is merged with the flow computer's existing historical data storage capabilities. Instead of creating a separate archival system, the flow computer integrates verification test results into its existing data structure and storage mechanisms. This merging approach enables comprehensive data archival while avoiding the complexity of duplicating infrastructure.
4Reliability
If flow meters have internal verification functionality, then measurement capability is improved, but interface capability with external systems deteriorates
Solution Approach 1:
The system implements a feedback loop where the flow computer receives verification test results from the flow meter, processes this information, and uses it to update system diagnostics and trigger appropriate responses. This feedback mechanism ensures that the internal verification functionality enhances reliability while the feedback processing layer maintains external interface capability through the SCADA system.

AI summary
Systems and methods to initiate a verification test within a flow meter via a flow computer are disclosed. An example method includes communicating, via a flow computer, a request to a flow meter to initiate a verification test of the flow meter. The example method also includes retrieving diagnostic data from the flow meter. The example method further includes logging a result of the verification test in a log of the flow computer, the result based on the diagnostic data.
