The topic for the February meeting is Interpreting Length of Stain Tubes. The speaker is Ron Roberson, Corporate Industrial Hygienist from Clearwater, Florida with Sensidyne, Inc. Ron will discuss the history, design and operation principles for length of stain tubes. He will then relay manufacturer's specifications for sampling procedures, specifically covering hydrogen sulfide, carbon dioxide, mercaptans, and water vapor. The water vapor section requires discussion of stain color interpretation and known interference's to a correct reading. A new ultra-low water vapor tube just developed will be unveiled. Where: Lafayette Petroleum Club When: February 16, 1998 Time: 6:00-6:30 PM - Social Half Hour Last month's January meeting was on January 20, not the 10th as reported in the January newsletter! If that's the reason only the board and a handful of members showed up, I apologize and take full responsibility. If it's not why you didn't show up, that's different. Didn't like the topic or didn't receive the newsletter? TELL US! We need to know if someone isn't receiving a newsletter or doesn't like meeting topics. Of course an alternate topic would really help everyone. Usually something a member wants to hear about is a topic many members what to hear about. That's why we have a measurement society - to discuss topics of interest to the members! |
As always, the meetings are the 3rd Tuesday throughout the year, except the summer. The January topic was Multiphase Measurement
and Meters by David West of Daniel Measurement and Control. The various
methods and approaches to measuring gas, oil, and water in a single
stream were discussed. Watch For Bad Solar Panels on EFM & Automatic SamplersCorrosion and delamination due to water
becoming trapped in the bottom frame of Amorphous solar panels causes
the unit to fail or charge poorly. The amorphous panels are black, compared
to the blue Crystalline models. Solarex has a 10 year warranty on these
units, and will exchange them for new panels. Look for a lighter color
of brown along the bottom of panel or blisters formed under the black
covering. The corrosion may not be obvious! A field test of the units,
using a 30 Ohm resistor and digital mulimeter will ensure all panels
are good. A copy of the test can be obtained from Solarex at 301-698-4200
- or come see the test on this and ni-cad batteries at the short course!
Booth Assignments Should Be Mailed Soon85 booth packets for the AFMS Short Course on April 7-8, 1998 are reserved and paid for. With the rest expected to confirm by this months end, a mailout of booth assignments, short course brochures, and a short course poster should happen in early March. This year, the 77 booths inside the ballroom are $375 each, while the premium 20 outside booths are $425 each. |

MEASUREMENT ON THE WEBWeb sites useful to our measurement membership. If you have other sites of use, please let us know at the AFMS phone/fax 318-993-AFMS. We are still waiting "with baited breath" for our own web site at http://www.afms.org.
The last web, don't use www, just http: Look for the AFMS Short Course ad in the January issue of the Oil, Gas & Petrochem Equipment publication! |
MEASUREMENT IN PRINT Pipeline & Gas Industry
TIP OF THE MONTH QUESTION: For each 4 BTU adjustment, is 1 BTU lost due to volume change for Fg? ANSWER: Normally yes, with one important exception. If the BTU was changed due to a change in oxygen, nitrogen, or any hydrocarbon, then the gravity change will offset the BTU change by about 25%. The exception is carbon dioxide. A reduction of CO2 also reduces the gravity, which causes even higher volumes, about .1% higher per 4 BTU. BTU adjustments caused by CO2 error then are: each 4 BTU adds 4.4 MMBTU with the volume increase. |
