A change of a reading or a set point value over long periods due to
several factors including change in ambient temperature, time, and line
voltage.
Hydrocarbon liquid that separates in a pipeline transporting gas from
the well casing, lease separation, or other facilities and drains into
equipment from which the liquid can be removed.
An electronic circuit that provides input to another electronic circuit.
A program that exercises a system or system component by simulating
the activity of a higher level component.
Software that controls a specific hardware device, such as interface
boards, PLCs, RTUs, and other I/O devices.
Large liquid particles
Contacts which neither break nor make a circuit. 0 Ohms.
Has no more than seven pounds of water per million cubic feet of gas.
Gas has less than 0.1 PPM of liquid at the coldest ambient condition
expected at the coldest point in the system. The liquid can be water, oil,
synthetic lubrication, glycol, condensed sample or any other non vapor
contaminate.
Digital Signal Processor.
A sensor assembly with two independent sensing elements.
Memory that can be sequentially accessed by more than one controller
or processor but not simultaneously accessed. Also known as shared
memory.
The ability to both send and receive data simultaneously over the same
communications line.
A pair of wires insulated from each other and with an outer jacket of
insulation around the inner insulated pair.
The total time to one on/off cycle. Usually refers to the on/off cycle time
of a temperature controller.
The Port Manager and communication engine of the SCADAvantage
System. This software can multiplex among several communication
formats and thus supporting several vendor's equipment over a single
radio frequency. It "pushes" new data to the SCADA database, saving
time and network resources by not transmitting redundant data. The
DVI includes the Totalflow WinCPC code and thus supports all
Totalflow software and functions – including WinCCU, TDS, PCCU,
Report by exception, cryout, etc.
This is the most common form of computer memory It needs to be
continually refreshed in order to properly hold data, thus the term
"dynamic."
See Electrically Erasable Programmable Read-Only Memory. Also
called EEPROM.
