Honeywell Smart Multivariable Transmitter/ Multivariable Analog Interface for Fuel Flow Measurement Flow Measurement in the Oil and Gas Industry

Problem: A major gas plant was using
a Moore 4-20 ma indicator/integrator
to obtain totals for fuel flows. Total
flow tabulation was labor intensive.


A customer was using a Moore
indicator/integrator to obtain total flows from a
Smart Multivariable Transmitter (SMV3000)
measuring a fuel flow. The Moore indicator
could integrate the SMV flow signal in the
analog mode and totalize the flow over time.
Unfortunately, the flow had to be totalized
manually at the end of each day, week, and
month. A method was needed to eliminate
remove manual calculations.
Recently, the plant underwent a detailed
study to identify areas where automation could
result in significant cost savings to the plant .
Solution: The Honeywell Smart
Multivariable Transmitter used with
the Multivariable Analog Interface
and the VPR 100 Video Recorder
used for automatic totalization.
The plant needed an inexpensive,
simple method for measuring and recording
fuel flows over several time periods. The Smart
Multivariable Transmitter (SMV3000) provides
measurement of differential pressure across a
primary flow element such as an orifice or pitot
tube, a process (static) pressure measurement
and a process temperature using either an RTD
or thermocouple. As the fourth process
variable, the SMV3000 provides a compensated
flow measurement based on the first three
process variables.
The Multivariable Analog Interface
(MVA141) manufactured by Vektron Corp.
allows all process variables to be transmitt
