Text File Interpretation
Information from line 1 indicates the date this file was created or last modified.
Lines 2 to 6 provide information to Birdfeeder 2 for Volume Units, Depth Units, High-High
Level, Display Precision and Spill Alarm Level.
The example above indicates:
1. The programming file was created on 23 November, 2006 at 8:42 am.
2. The transmitter is programmed to display barrels (BBL).
3. The depth units used for the chart is inches (in).
4. The High-High (HH) alarm is programmed for 231.0 BBL (see line 7 above) at a
depth of 78”
5. The Finch display is set for one decimal place of precision.
6. The Spill alarm is set at a distance of 8” from the tank top or a depth of 79” (see line 8
above) and a volume of 232.2 BBL. The actual Spill level is 7.5” or 79.5” and a
volume of 232.75 BBL. Spill Level=8 is an indication that this table was created for a
dual rod transmitter. Any other Spill Alarm level of 2.5” to 15.5” indicates a coaxial
transmitter.
Additional information is needed to complete the programming in Birdfeeder 2. Customer
records are required to determine the coaxial transmitter Spill Alarm Reset. The most
common setting is Auto-Clear. Mechanical details such as riser or sump installation may
be required to convert to a Birdfeeder 2 formatted file (.STB). These details and the
optional 4-20mA settings may be supplied by the customer.
