2.13 FUEL OIL LEVEL-INDICATION AND LEAK DETECTION:
A. General: The tank liquid level management system shall be a fully integrated
microprocessor based system for 1 to 8 tanks. The system shall continuously monitor the
liquid inventory of each tank. System shall include an individual selectable display for
product level in inches, product volume in gallons, level of water, and temperature of
product for each tank. The visual alarm condition shall be displayed until the condition is
corrected. The system shall retain in memory the last 3 alarm conditions by tank and last
10 deliveries by tank. The system shall include battery back-up to retain data stored in
memory during loss or interruption of power for up to ten years. System shall monitor
liquid levels and product temperature for tank leak test and/or theft test during tank
quiescent periods. Inventory reports containing product levels, volumes, water level, and
product temperatures, alarm history reports, delivery history reports, theft test results, and
tank leak test results. Reports shall all be presented via a RS-232 data output port built-in
printer. Reports shall include site name/location, date, and time. System shall operate on
110-120 V., 60 hertz, A.C. current.
B. Control Console: Control console shall be constructed in a wall-mountable steel enclosure
complete with a 5 digit, 0.81, high, 7 segment LED display for inches and gallons of
product of inventory, level of water and temperature of product. Control console shall
include individual visual LED light and audible alarm for programmable high level, low
level and water presence alarm conditions for each tank. Two alarm relays, reach rated
SPDT-3 amps, shall be provided standard for external control functions. Provide
additional alarm relays, two per tank (maximum of 16). Audible alarm shall include a
disable switch. Touch key pad shall be splash proof dual purpose, accommodating tank
and function selection as well as system programming functions. Control console
calibration, set-up and diagnostic trouble shooting. The console should provide SPDT
switch contacts rated 3 AMPS at 120 VAC, for each leak sensor, for controlling external
devices. Electrical circuitry to tank mounted sensors should be low current rated
intrinsically safe for hazardous areas.
