5.2 Inventory enquiry via network and browser
The stock of a tank farm should be measured and monitored continu-
ously. The measured values should be available to the scheduler and
the sales department. In addition, a message should be triggered
automatically if a level drops below a certain value.
One or more signal conditioning instruments with Ethernet interface
enquire the respective sensors cyclically. The measured values are
processed in the signal conditioning instrument and transferred in the
requested form and unit to the integrated web server. The measured
values can now be displayed on the computer of every user in the
company network. In addition, the required minimum quantity is en-
tered for each vessel. An e-mail is sent to the appropriate person via
the company-internal mail system if a level falls below a certain value.
