ON-SITE FLOW METER CALIBRATIONS

Description

Flow Technology, Inc. (FTI), a leading
manufacturer of precision flow measurement instruments, systems and
calibrators, today introduced the "Gecko" Flow Transfer Standard-the next
step in on-site flow meter calibration.  The compact Gecko system utilizes
the EZ-LINK(tm) portable interface box and EZ-CAL(tm) menu-driven software
for inline comparison calibrations with the unit under test (UUT).

Designed for both liquid and gas applications, Gecko is an alternative to
costly primary standard calibrators for in-house calibrations or
verifications.  The system consists of software and a USB interface box
which allows the user to interface with a computer of their choice.  Master
flow meters can be supplied by Flow Technology or the user can choose to use
virtually any meter technology they desire for a master reference meter.

Gecko's EZ-CAL software receives inputs from the master flow meter,
temperature sensor, and pressure sensor (gas systems) for calculating both
volumetric and mass flow units.  Overall system accuracy is dependent on
several factors, including master flow meter calibration, repeatability and
primary standard accuracy; as well as temperature/pressure sensor
accuracies.  This fundamentally allows the user to tailor the accuracy of
the system to meet their needs through the level of master sensors they
choose to utilize.

The Gecko system can be installed into an existing application utilizing the
flow source and actual conditions of the liquid or gas.  In addition, a
bypass system can be built into the application for ease of installing the
master meter with flow straighteners for calibration of the UUT.  Once the
calibration is complete, the master flow meter can be replaced with a
recommended spool piece.  The bypass approach maximizes accuracy while
minimizing expensive downtime in production schedules.

There are no application limitations with the Gecko system with the correct
master flow meters, piping, sensors and calibrations.  Thanks to recent
advancements in electronics, Flow Technology has incorporated additional
input capabilities for other flow meter technologies to be used as master
flow meters.  This gives the metrologist the ability to choose the flow
meter design best suited for the process.  Flow Technology also offers
custom carts, stands and flow loops with multiple master flow meters.
