Thanks to Don Mayeaux with A+ Corp for his discussion on recnet advances in natural gas sampling and hardware at our October meeting. Don discussed the conditions that cause liquid to condense in natural gas samples and some remedies.

Bob Chaisson with Kelly Completion Services phoned our President, Danny McFarland to volunteer as Monitor Chairman for the short course on April 7-8, 1998! Be sure to thank Bob personally, especially by signing up to monitor a class or three you intend on attending when the schedule is out.

Speaking of the schedule, by the November meeting, Phil Marinde, Daniel Measurement & Control (318-232-8949) will have convened his first meeting of the Speakers Committee. The most important work this group does needs help from the entire society membership. This help is the easiest to do and is personally rewarding - suggesting topics for the short course and monthly meetings! The longer notice we give potential speakers, the more likelihood they can teach the class. The scheduling of their time to teach and write a topic is essential to speakers these hectic days. Get out your wish list!

Some research of the USL scholarship fund found several unknown items. There was a $3000 "cash available" fund, separate from the principle. Each year, USL invests all the money available and earns about 10% interest. 5% of this is used for our scholarships, the remaining going to this cash available fund. The $3000 was moved to the principle section, with instructions to automatically do this with any remaining cash from investments each year. A $500 addition was added to the fund at the last meeting, bringing the principle to about $17,000. For those that didn't know, the scholarships go to industrial technology juniors and seniors in the school of engineering. We have one of the few (if not only) sholarships to this field.

TIP OF THE MONTH

QUESTION:

A small leak is detected on the manifold system of a gas flow computer. "Snooping" the tube and fittings reveals no bubbles from the soap. How can the test learn which side of the manifold the leak is?

ANSWER:

Even a minute leak can be detected with a flow computer indicating differential pressure. The manifold can be returned to normal service, then shut both tap valves. If the observed DP falls, the leak is on the high side. Conversely, if the observed DP rises, the leak is on the low side. The manifold may then be blown down and all fittings tightened on the suspect side.

NOTE: "Snooping" a manifold system with small gauge lines can cause the DP to rise or fall due to temperature change caused by the liquid soap. Do not use the method above while snooping.
