Inline Fluidic Sensor Calibration via External Fluid Sourcing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operational lifetime of in-line fluid sensor systems is limited by the availability of calibration fluid and the cost of storing and maintaining a large volume of calibration fluid.
Innovation Solution
The system uses a method involving two calibration fluids, where a first calibration fluid is stored in a calibration compartment and a second calibration fluid is sourced externally or from a treatment line, allowing for calibration and extended operation without the need for a large internal calibration fluid storage.

1Duration of action of moving object
If a large volume of calibration fluid is stored in the fluid sensor system, then the operational lifetime is extended, but the footprint and storage cost increase
Solution Approach 1:
The patent extracts the second calibration fluid from the fluid sensor system by obtaining it from an external source (treatment line) rather than storing it internally. This allows the system to perform calibration without carrying large volumes of calibration fluid, thus extending operational lifetime while minimizing storage volume requirements.
Solution Approach 2:
The treatment line fluid is made to serve dual purposes: both as the sample fluid being treated and as the calibration fluid for the sensor. This multi-functionality eliminates the need for separate calibration fluid storage, reducing the system's footprint while maintaining calibration capability.
2Measurement precision
If calibration fluid is frequently replenished, then sensor accuracy is maintained, but the system complexity and maintenance cost increase
Solution Approach 1:
The treatment line serves multiple functions by providing both the sample fluid for treatment and the calibration fluid for sensor calibration. This eliminates the need for separate calibration fluid storage and handling systems, maintaining sensor accuracy through regular calibration while reducing overall system complexity.
Solution Approach 2:
The system uses its own treatment line fluid to calibrate the sensor, making the calibration process self-sufficient. The treatment line automatically provides calibration fluid without requiring external intervention or separate calibration fluid management, thereby maintaining accuracy while simplifying the system.

AI summary
A fluid sensor system and method of operating the fluid sensor system is disclosure herein. A fluid sensor device of the fluid sensor system can be connected with a treatment system in-line. The fluid sensor system may receive a second solution different from a first calibration fluid to use as a calibration fluid to reduce costs associated with storing calibration fluid inside the fluid sensor device prior to use with the treatment system.
