6.11.2.2 Method 2 current flow
The calculations are during the batch instead of at the end of the batch. When an error occurs, this
error is calculated using the current gross flow as long as not all 5 channels are down (then max flow is
used). This leads to less overrated batch volume error% values.
Because the error % is calculated during the batch using the current gross flow it is not possible to
recalculate this method at the end of the batch. Only method 1 can be recalculated.
This method prevents overrated batch volume error% during startup where low flow rates and path
failures due to gas outbreak can co-exist.
6.12 Continuous Pipeline Measurement tickets
When the BATCHING_ON mode is in Continuous Pipeline Measurement no confirmations are asked
after printing the ticket.
If a new ticket has failed in printing it is asked to reset. But if no reset is made then the next ticket will
just make the reset and start printing the next ticket.
The previous ticket can then be printed as described in paragraph: Reading / Printing previous batch
ticket
There are two options for continuous Pipeline measurement:
• 3 Auto reset of totalisers, errors, averages etc between tickets
• 4 No auto reset of totalisers, errors, averages etc between tickets, but possible on demand.
(clnt0300.dat file section 12.1 option 3 or 4)
For Continuous Pipe Line Measurement the ticket automatically is printed, counting the hours starts
from HOUR_START (clnt0300.dat file section 12.3)
For Continuous Pipe Line Measurement the ticket automatically is printed every HOUR_INTERVAL,
but if interval 0 is installed than tickets are only printed on demand (clnt0300.dat file section 12.4)
