Utilizing a two-meter manifold control system, the portable, automated Flow Gator calibrator (photo) operates in single viscosity fluids from 0.1 to 310 gal/min. Calibrations in multiple viscosities can be achieved from 0.35 to 310 gal/min. Instead of removing flowmeters from service for recalibration, the Flow Gator flow-transfer standard allows users to bring the calibrator to the flowmeter. This flow calibrator is intended for inline calibration and validation of meters using the actual process liquid. Rugged, lightweight and compact, the Flow Gator incorporates handheld electronics. Two dual-rotor turbine flowmeters, which provide exceptional repeatability of ±0.02%, enable the Flow Transfer Standard system uncertainty to be <±0.25% of reading. The Flow Gator system’s intuitive, menu-driven calibration software enables end users to create calibration data files, which can be up loaded to a PC for storing historical calibration data. — Exact Flow, Scottsdale, Ariz.
