RESEARCH PROGRESS REPORT
UA-06-S2018 STATUS: Continuing, Requesting Additional Funds
Relationship to Technology Roadmap: Smart Water Distribution Systems
Objectives:
Key Findings:
Configured digital and analog sensors to provide correct output measurements
LabView Development:
V SCAN test and batch test windows
Channel configuration window
Reference document
Built custom test beds
Tested phase 1 of set-up and configuration of corrosion station
Produce an accurate estimate of the Instantaneous Corrosion Rate (ICR) of representative mild steel and copper coupons
Create a continuous online corrosion monitoring station
Modify one of Tucson Water’s corrosion field stations to the new lab tested configuration and equipped with continuous online monitoring and recording instrumentation
Approach:
Project Status:
Continue to evaluate corrosion in a Simulated Field Setting
Download sensor data directly to XP computer
Acquire Ana-Pro Finger print software
Configure Keithley outputs using Channel configuration window
Test custom test beds
Acquire reference electrodes and test coupons
Test phase 2 of set-up and configuration of corrosion station
Continue bridging the gravimetric and electrochemical methods to accurately determine the ICR in the lab
