and You will get a first information under
half a day.
Swedish 0800-1200 and english 1200-1700.
Price 2500 SEK + taxes.
Incl lunch and coffe.
Please sign in before 140614 if You want
to join the seminar, by sending an email

to mail@matematica.se
welcome!
Matematica will deliver a 2,5 flowmeter dpns (double precision non stop)
system for a Skangass and Preem natural gas terminal in Lysekil/Sweden.
-The system will calculate the mass and energy-flow threw 3 pipes.
-Total uncertainty of the complete system sensational 0.3%!
(Including transmitters, pipe and computer).
-The dpns system combines the strength from 2 types of flowmeters.
1. The reliabality of a standard verified flowmeter, orifice.
Advantage; If everything is done according to standard,
You know that the calculated mass/energy flow value is correct.
2. The very high precision of a commercial flowmeter,
a US-flowmeter from Krohne.
Advantage; Very high precision if the manufacutrs numbers
can be realized. But You can only hope that these numbers
can be realized.
The different flowmeters will check each other and the software
will calculate the most plausible flow threw the pipe!
-Every single component of the system can be taken out of
operation for service calibration and more while the dpns-system still
working.
-The system will indicate when the time has come to calibrate
every single transmitter!
-The total system with transmitters, signal transmission and
calculations will have a total uncertainty of 0.3 %!
-The calculation system i based on a Siemens PCS 7 CPU.
Please take a look on GNG_2 page for more information.

Matematica gets a function block order from AGA/LINDE.
It's a Siemens PCS7 block called GC repair that filters the
signals from a natural gas chromatograph.
Whenever the signals from the GC are unlikely to be correct
the GC block stops the signals from passing the GC repair block.

Matematica releases version 2.0 of the gas analyzer diagnostic block
GC_repair_2. This PCS7 function-block analyzes the signals from the GC
and if one or more signals are impossible, this GC_repair block will
select the most recent signals from the analyzer without problems and send
them to the other blocks for calculations. The error dtection consists of
2 parts;
1. Tecnical limits for the signals like min/max and max speed of change
2. Statistical analyse of the signals from the GA/GC.
If one or more signals are statistical unlikely, the block will use the most
recent signals without tech/stat errors and send them to the rest of the
calculations;
