(In our continuing effort to clarify any misunderstandings or misperceptions regarding railroad tank car gauging devices and the future prevention/elimination of Non Accidental Releases (NAR)s, MGM extends the offer for our readers to add their comments to the following story as it relates to slip tube, magnetic, electronic and/or other style level gauging devices. Please use the MGM Feedback Form to express your views and suggestions)
For over 60 years, MGM has manufactured slip tube gauges to provide an accurate fuel level reading when loading liquefied petroleum gas (LPG) tanks. During this era, these precision instruments were considered to be the most accurate way to gauge LPG tanks (aboveground storage, railroad and barge vessels). Accurate liquid level gauging was accomplished by setting the slip tube gauge to the desired loading level and then watching the commodity discharge out of the control valve on top of the gauge rod. When the commodity being discharged changed from a vapor to a liquid, the preset loading level had been achieved.
As technology changed over the years, and with todayâs growing concerns about a cleanerenvironment, MGM continues to work closely with industry customers and regulatory agencies to move towards closed loading of these commodities to prevent and eliminate product discharge to the atmosphere! While there are literally tens of thousands of slip tube gauges still installed on tanks, barges and rail cars worldwide today, MGM chose to design & manufacture the widely accepted magnetic style gauging device (MGM Model 275 Magnetic Gauging Device) for the railroad tank car industry starting in 1990. MGM also continues to forge ahead with the development of new level gauging product technology for the future.
FACTS:
More than 60 years ago, slip tube style gauges were intentionally designed and accepted by industry to discharge commodity as a visual indicator of product level in a closed tank. When properly operated & maintained, these devices should not leak when stored in their closed position! While it is unlikely that you would experience any functional problems with your slip tube gauge, please contact MGM Tank Car Co. immediately for assistance and recommendations should you desire! We will be more than happy to help you in any way. In addition, should you wish to replace your slip tube gauge with a magnetic or other style level gauge, contact MGM Tank Car Company for a quote on our Slip Tube Exchange Program (S.T.E.P.) offer.
