Natural Gas Flow Measurement - In Venezuela.
Hoffer Flow Controls has recently supplied two computerized
natural gas turbine flow measuring systems to Venezuela's
gas industry. These systems accurately measure "mass"
flow rate and total. Venezuela
has enormous gas resources and measuring it accurately is
critical because of its value. In one basin
alone, there are approximately 3000 wells that require regular
flow rate and flow total verification.
The two units, one for low
to medium flow and one for medium to high flow were
designed and engineered to be mobile and to measure
standard cubic feet per day. Connected at the well head
atmospheric discharge, this sophisticated turbine gas
flow computer performs temperature and pressure compensation
and is accurate to ± 2%. Repeatability is ±
0.25% over the repeatable flow range.
Each mobile unit has two turbine flowmeters and a flow
computer to measure the changing extended flow rates
between well heads. Operated on a 24 volt rechargeable
battery system |
 |
the operator can independently move from location to
location. Each computer system is equipped with an RS232
communication port and Windows compatible software.
This enables the operator to download his flow information
from each well to a laptop computer for ongoing well
performance reports.
Despite the fact that new construction materials and
design changes have improved turbine flowmeter performance,
the most significant changes can be found in computerization.
This has truly made a difference in creating a high
accuracy flow measuring system.
