Environmental Monitoring Solutions Pty Ltd [EMS], in collaboration with Monash University, has completed a six-month research study on geo-barometric influences of fuel behaviour.
Fuel expands and contracts with temperature, that is a simple and well-understood phenomenon, however, understanding the real impact of temperature changes when thinking about detecting fuel system leaks and vapour emissions can become fuzzy.
The springboard for the study was the availability of high definition – high-frequency fuel data [fuel height/volume and in-tank and ambient temperature].
The study considered gas stations across large and small networks in a number of geographic locations to provide a balanced representation of the very different barometric conditions across a country and from country to country in the southern hemisphere.
This allowed the researchers to dynamically plot the impact of in-tank behaviour due to fuel movements, where transport times and in-tank settling can make major impacts due to the difference in above and below ground fuel temperatures.
The following three examples illustrate the temperature difference across one region punctuated with delivery periods.
Example 1 — Moderate Climate Site 36 Degress from Equator
Whilst the engagement with Monash is complete, the project continues headed up by Dr Li Chik from the EMS research team that will review northern hemisphere countries during the cooler months.
The research outcomes are planned to become embedded functionality for the benefit of both Greenscan® and Fuelsuite® clients.
