Flow Meter Automatic Data Logging Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow meters require manual user intervention to log data, which can lead to missed recordings if the user forgets to execute the logging operation, resulting in unreliable data storage.
Innovation Solution
A flow meter that automatically logs data by incorporating a detection element, flow rate calculation part, control storage part, and time measurement part, which initiates logging based on predefined logging start definition information upon startup, ensuring continuous and reliable data storage without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual user intervention is used to log data, then the device complexity is reduced, but the reliability of data logging deteriorates due to missed recordings when users forget to execute logging operations
Solution Approach 1:
The control part is pre-programmed with logging start definition information that automatically triggers logging operations at predetermined timing without requiring user intervention. This preliminary setup ensures reliable data logging while avoiding the need for complex manual control interfaces.
2Reliability
If automatic logging is implemented, then the reliability of data logging improves, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The flow meter performs self-service logging by automatically detecting flow rate data and storing it in the log storage part based on predetermined timing. The system serves itself without external user intervention, ensuring reliable logging while keeping the control mechanism straightforward.
Solution Approach 2:
The logging function is merged with the existing control part and detection element, rather than being implemented as a separate complex subsystem. This integration achieves automatic reliable logging while minimizing additional device complexity.
3Ease of operation
If manual logging operation is required, then the ease of operation deteriorates due to additional user steps, but the device complexity is kept lower
Solution Approach 1:
The system eliminates the need for user logging operations by implementing self-service automatic logging. The flow meter independently performs detection, calculation, and storage of flow rate data, significantly improving ease of operation without requiring complex user interfaces.

AI summary
Provided is a flow meter capable of logging data more reliably. In this operation, a detection element repeatedly detects a physical quantity related to a flow rate of a fluid flowing in a pipe in a predetermined sampling cycle. Based on physical quantities, a calculation part sequentially calculates the flow rate of the fluid in the pipe. Further, a time measurement part calculates the time. A control storage part is caused to store a logging target, a logging cycle, and logging start definition information. Based on the logging start definition information, a control part automatically starts logging of the logging target in response to startup of the flow meter, and causes a log storage part to store the time measured by the time measurement part and a numerical value of the logging target in association with each other in every logging cycle.
