100
The Petroleum industry established this at 42 U.S. gallons
What is a net barrel
100
This part of the Turbine meter turns at a speed proportional to the rate of flow
What is rotor
100
These devices measure the vibrations in Coriolis meters
What are sensors
100
Densitometers are proven with this
What is Pycnometer
100
These devices create optimal flow patterns necessary for accurate measurement
What are flow conditioners
200
Dynamic volumetric measurement requires that product be in the liquid state and free of these
What are vapor bubbles
200
This Turbine part boosts and conditions the turbine output signal to a level suitable for transmission
What is pre-amplifier
200
This part of a Coriolis meter divides the flow evenly between the two flow tubes
What is flow splitter
200
This type of device is used to calibrate liquid meters
What is a prover
200
This type of stream imperfection is known for its corkscrew flow pattern caused by piping convolutions and obstructions
What is swirl
300
Performing this task is a critical element of accurately determining the components in a NGL stream (prior to analysis).
What is pulling a sample
300
Total number of pulses produced for some known amount of flow
What is K-factor
300
This type of wave represents the motion of the tubes
What is Sine
300
This process establishes the Base Prover Volume (BPV)
What is waterdraw
300
This type of instrumentation captures data from transmitters in order to determine flow rates
What is a flow computer
400
This type of NGL measurement is not affected by temperature or pressure
What is mass
400
The total number of these, over an integrated period of time, represents the indicated volume metered
What are pulses
400
This is the only time that Sine waves will coincide
What is no flow
400
These types of transmitters must be checked at three points (zero, span and mid-range)
What are pressure transmitters
400
This device is used to prevent flashing and to maintain 1.5 bubble point on the meter
What is backpressure regulator
500
The Petroleum industry says a net barrel must be corrected to 60 degrees Fahrenheit and this
What is equilibrium vapor pressure (EVP) of the product
500
This term defines how close a Turbine meter is compared to the actual flow
What is accuracy
500
This is one of the only flow imperfections that impacts Coriolis meters by causing repeatability issues and over-registering
What is pulsation
500
Calibration is required when a temperature transmitter is off more than this amount
What is 0.2 degrees Fahrenheit
500
This happens when the temperature of a product produces enough vapors to produce a flammable mixture with air
