2103650-001 – rev. AB
A change in which a substance changes from one physical state to
another but no substances with different composition are formed.
Example Gas to Liquid - Solid.
Proportional, Integral, Derivative. A three mode control action where the
controller has time proportioning, integral (auto reset) and derivative
rate action.
A ceramic material that has piezoelectric properties similar to those of
some natural crystals.
Liquid hydrocarbons that have condensed from gas to liquid as a result
of changes in pressure and temperature as gas flows in a pipeline.
Pipeline condensate only remains as a liquid under high-pressure
conditions and would vaporize at atmospheric pressure.
All liquid hydrocarbons and other products (including sulfur and
excluding residue gas) recovered in a gas processing plant.
See Programmable logic controller
A technique used to optimize gas production. A Steel plunger is
inserted into the production tubing in the well. The flow is turned off and
this shut-in causes plunger to fall allowing fluid to collect above plunger.
Different techniques are used to decide how long to shut in and flow the
well.
In electricity, the quality of having two oppositely charged poles, one
positive one negative.
A snapshot view of the readings taken by the Totalflow equipment.
A communications connection on a computer or a remote controller. A
place of access to a device or network, used for input/output of digital
and analog signals.
An increase in resistance due to an increase in temperature.
Opens circuit when high current condition occurs. Closes when
condition no longer exists. Replaces typical fuses, which require
replacement when blown.
Program Organization Unit. This is Softing's term for an 'independent
programming unit'. Programs, functions, etc.
A separate unit or part of a circuit that supplies power to the rest of the
circuit or to a system.
Acronym for parts per million.
The contractual, regulatory or standard ambient pressure at which
natural gas is measured or sampled expressed in psia (pounds per
square inch absolute).
Difference in pressure between any two points in a continuous system.
Pressure testing at different levels of pressure. Used for comparison
purposes.
