About

Ph.D. in math with extensive work in the field of equations of state (see www.researchgate.net/profile/Arnold_Liu) , ultra-high precision aerospace fluid flow metrology (including design of flow calibration systems rigorously based on "fundamental properties", e.g. i.a.w. IAPWS-95/IAPWS-IF97 for water), and pipeline leak detection by mass / standard volume balance (as described in the Pipeline Rules of Thumb Handbook, ISA Instrument Engineers Handbook, Journal of Flow Metrology, on the Pipeline Safety Trust's website at www.pstrust.org/docs/massbalance_ld.pdf, etc.)

The oldest and least maintained part of any city's infrastructure are its water mains.  With average water leakage in aging water distribution systems commonly exceeding 20% -- which is frequently more than can be saved by even the most stringent conservation mandates and/or consumer-side conservation efforts -- the distribution-side requirement to lower flow measurement uncertainty via calibration is of supreme importance, providing the fundamental basis for accurate/reliable water audits and early low level pipeline leak detection, location, and prioritization.   Early low level detection of leakage and the remediation thereof frequently saves decades of slow seeping water losses.

Calibration of measurement systems is universally required by all quality management systems, e.g. ISO-9000/9001/9002, ANSI/ASME NQA-1, MIL-I-45208, etc. Moreover, the resulting minimization of processed water leakage loss achieved through improved measurement is the most cost effective means of augmenting/increasing and insuring distribution system water supply and sustainability.  Although recycling and desalination may be used to augment currently available conventional water supplies, they are several times more costly -- and such expensive forms of "new" water should not be put into water mains that continue to leak.   Additionally, by minimizing processed water loss/leakage during transportation, corresponding water treatment and energy savings can be achieved.
