Flow standard replaces expensive calibrators

Flow Technology product story

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.
Flow Technology has released the Gecko flow transfer standard on-site flow meter calibration.
The compact Gecko system uses the EZ-Link portable interface box and EZ-Cal 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 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 allows the user to tailor the accuracy of the system to meet their needs through the level of master sensors they choose to use.
The Gecko system can be installed into an existing application using the flow source and actual conditions of the liquid or gas.
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 maximises accuracy while minimising 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.
