Term Definition
Programmable Read
Only Memory
Computer memory in which data can be routinely read and written to.
ROM is used for storing data or programs (e.g. operating systems) and
characteristic files on a semi-permanent basis.
Programmed I/O
The standard method a CPU uses to access an I/O device-- each byte of
data is read or written by the CPU.
PROM
See Programmable Read Only Memory
Propane (C3H8)
A saturated hydrocarbon (alkane) gas, the molecule of which is composed
of three carbon and eight hydrogen atoms. Propane is present in most
natural gas and is the first product refined from crude petroleum. It has
many industrial uses and may be used for heating and lighting. Contains
approximately 2,500 Btu per cubic foot.
Protocol
A formal set of conventions governing the formatting and relative timing of
message exchange between two communicating systems.
PSI
Pounds per Square Inch.
PSIA
Pounds per Square Inch Absolute. Absolute pressure uses a perfect
vacuum as the zero point. A perfect vacuum is 0 PSIA.
PSIA=PSIG + Atmospheric Pressure.
PSIG
Pounds per Square Inch Gauge. Gauge pressure uses the actual
atmospheric pressure as the zero point.
PTB
Physikalisch Technische Bundesanstalt (German for Physically Technical
Federal Institution) or German Technical Institute for Certification.
PTC
See Positive Temperature Co-efficient Fuse.
Pulse Input
An digital input to a meter (usually a turbine) that is used to measure
pulses over a time period. This calculates volume and flow rate for each
period of time.
Pulse Mode
An operational mode used by the LevelMaster for measuring single float
levels by transmitting a pulse to the primary windings, reading the voltage
level on both the primary and secondary windings and using a calculation
whereby one is subtracted from another to determine the single fluid level.
Radio Frequency
RF for short. That part of the spectrum from approx. 50kHz to gigahertz.
Radio Frequency
Interference
Electromagnetic radiation which is emitted by electrical circuits carrying
rapidly changing signals, as a by-product of their normal operation, and
which causes unwanted signals (interference or noise) to be induced in
other circuits.
RAM
See Random Access Memory. Also referred to as RAM Disk.
RAM Disk
A lithium backed storage chip. Also see Random Access Memory.
Random Access
Memory
Semiconductor read/write volatile memory. Data stored is lost if power is
removed.
Rated Capacity
The number of ampere-hours a cell/battery can deliver under specific
conditions (rate of discharge, cut-off voltage, temperature).
