LEAKS Occur when holes develope in the tank wall or piping system, or when the seals around
tank accesses or pipe fittings age. The probability of a leak increases with age. There are two
types of leaks: 1.) Product contamination from high ground water levels, and 2.) Environmental
contamination from product leaking out of a containment area / tank. Leaks pollute the
environment and create serious health and safety hazards.
LEVEL The actual physical height of the liquid in the storage tank in inches, or centimeters.
Level is determined by the position of the magnetized FLOAT on the probe.
LOW BRINE An alarm from a special TSP-HIS leak detection sensor. This sensor monitors the
brine for changes in level within the hydrostatic interstitial reservoir.
MAGNETOSTRICTIVE Interaction of magnetic fields along a special conductor within the
probe and from the magnetic float that is used to measure exact distances / liquid level.
MONTHLY COMPLIANCE A regulatory requirement and proof thereof, for at least one passed
leak test per month (this is usually a 0.2 gph leak test).
NET The temperature compensated, product volume within a tank. NET is temperature
compensated per API standards (to 60 degrees F, or 15 degrees Celsius for petroleum products).
OUTPUT GROUP / OUT GRP / OG A collection of one or more alarms that are linked
together to control an output device (such as a horn or light).
PERCENT The percentage of product within the tank in respect to the tank capacity.
POS An abbreviation for: a Point Of Sale terminal, or position.
PROBE A sensor-probe that is installed within a UST. The probe measures the product
TEMPerature from sensors within its’ shaft, and liquid LEVEL from the position of the FLOATs
along its shaft.
PROD An abbreviation for PRODUCT.
PROBE SYNC A term to describe a loss of synchronous data from the probe (usually because
of a stuck float, corroded, wet or broken cable wires, or probe failure).
QUIET TIME The inactive period between dispenses.
RELAY A device that consists of an electrical solenoid coil, and mechanically-linked switch
contacts. When voltage is applied to the relay coil it activates like an electromagnet, and
moves the contact switch positions (off to on or on to off). Therefore, any device that is
wired to the relay contacts also turn on or off along with the control relay.
ROM (TS-ROM) An external, 4 or 8 channel, Relay Output Module BriteBox that connects to
the console.... relay(s) can be activated in response to programmed alarms.
RTD An abbreviation for the Resistive Temperature Detectors ... in a liquid level probe shaft.
SCALD An abbreviation for a special Statistical Continuous Automatic Leak Detection tank test
that runs continuously between the periods of product dispensing.
