3.45.6 - Jul 11, 2011 |
| 1. |
Fixed units for liquid
volumetric flow @ flowing conditions. Units
setting was corrupted in Release 3.45.0. This
release fixes the problem. This error has a
potential impact to accuracy of calculation only
when using the described flow units. |
| 2. |
For volumetric flows for
liquids, changed l/h to exact conversion between
m3/h and l/h instead of correlating to liters of
water at 39 degF/4 degC. |
| Release
3.45.5 - Jun 27, 2011 |
| 1. |
Fixed units presentation for
orifice bore and meter differentials to display
properly when temperature units are mixed between
process temperature and dp reference temperatures
for both orifice meter bores and differential
pressures. Cosmetic fix only. Did not impact
accuracy. |
| 2. |
Fixed bore reference
temperature to display correctly (68 degF / 20
degC) only. Was displaying dp reference
temperatures for certain conditions. Cosmetic fix
only. Did not impact accuracy of calculation. |
| Release
3.45.4 Fixes & Changes - June 20, 2011 |
| 1. |
Reprogrammed the Meter Type
and Meter Style to print with Lo Loss Flow Tubes.
Old routine of setting text string for these
variables was no longer functioning for the
calculation print routine. |
| Release
3.45.3 Fixes & Changes - Jun 02, 2011 |
| 1. |
Corrected code logic to
correctly calculate uncertainty for orifice
plates where beta > 0.75. Program was cutting
off at betas > 0.75 and providing uncertainty
only for pipe, etc. |
| Release
3.45.2 Fixes & Changes - May 01, 2011 |
| 1. |
Added test for noise < 30
dB for minimum detectable noise. If noise is less
than 30 dB, set noise = 30 dB. |
| 2. |
Eliminate error in displaying
molecular weight for gas-volume-density-base
calculations. |
| Release
3.45.1 Fixes & Changes - Apr 20, 2011 |
| 1. |
Added MW to critical drop
equations for gas/vapor base and standard/normal
volumetric flows. Program was not functioning on
this equation without MW. |
| 2. |
Added error trap for Beta >
0.9 for critical drop ofifices. Beta should be
< 0.5 for thick and square-edged orifice
plates and < 0.25 for ASME flow nozzles and
ISO torroidal flow nozzles. |
| 3. |
Added warnings to thick plate
orifices for critical drop equations when beta
exceeds recommended design allowances, i.e., beta
< 0.5 for thick plate and square-edged
orifices and beta < 0.25 for ASME flow nozzles
and ISO torroidal flow nozzles. |
| 4. |
Fixed text for downstream
pressure for critical drop calculation screen
when calculating flow rate to read
"Downstream Pressure, Pf2 <." Screen
was reading "Permanent dP Loss =" which
was incorrect for this sizing method. |
| Release
3.45.0 Fixes & Changes - Apr 06, 2011 |
| 1. |
Fixed unit conversion for 1
m3/m and 1 m3/h to convert to 999.972 liters/min
and 999.972 liters/hr respectively. |
| 2. |
Another glitch related to
Release 3.44.2, Fix item 1. Had errant Patm term
that failed the logic check erroneously. Released
as 3.44.5 - Mar 23, 2011 |
| 3. |
Fixed another glitch left over
from Release 3.44.2. Program would give erroneous
Error 22 message for indeterminate results due to
sonic flow conditions. It was giving this error
for liquids as well due to error in logic
trapping this error condition. Additionally, the
units for dP were not properly converted from in
WC in determining the downstream pressure
conditions. Released as 3.44.4 - Jan 09, 2011. |
| 4. |
Fixed the Error 1007 problem
in Release 3.44.2 which prevented opening any
existing database files created with prior
versions. Released as 3.44.3 - Jan 05, 2011. |
| 5. |
Added Error No. 22 to trap
indeterminate conditions when the calculated
downstream pressures are < 0 psia which is not
possible. Released as 3.44.3 - Jan 05, 2011. |
| 6. |
Reformated some of the
pulldowns in the dialog screens to display all
units without a slider bar, etc. Released as
3.44.3 - Jan 05, 2011. |
| 7. |
Fixed orifice plate discharge
coefficient standard - 4th bullet - to display
ASME-MFC-3Ma (2007) which is the latest instead
of ASME-MFC-3M (2004). Printout always printed
correct standard. Released as 3.44.3 - Jan 05,
2011. |
| 8. |
Fixed program output for
calculation print outs for pressure drop
restrictions for
gases/vapors with the property set to densities
to not print Mw = 0. Mw should not
print for this fluid. Released as 3.44.1 - Nov
07, 2010. |
