Accurate Flowmeter Calibrations in the Field – Made Easy

Instead of removing flowmeters from service for recalibration, the Flow Gator flow transfer standard allows users to "bring the calibrator to the flowmeter." This portable, low cost, documenting field flowmeter calibrator is intended for in-line calibration and validation of flowmeters using the actual process gas or liquid.

The advanced Flow Gator incorporates hand-held electronics, thus eliminating bulky interface boxes and the need to carry a laptop computer into the field. Paired with an Exact Dual-rotor turbine flowmeter, which provides exceptional accuracy of ±0.10% of reading, this system represents a superior field calibration solution.

The Flow Gator flow transfer standard is designed for exceptionally wide flow ranges, and can be used for manifold control involving multiple flowmeters. The calibrator reads signals from the master meter, the flowmeter under test, and a fluid temperature sensor. It automatically selects the appropriate master meter based on the current flow rate. Flow conditioners are built in to the manifold as well as the temperature sensor.

The automated Flow Gator system, with is intuitive calibration software, has become the standard for the U.S. Navy, Marines and Air Force. This software enables end users to compile flow data and save information of interest. Users can download reports showing data points for the meter under test, and compare that information with output from the master meter. They can also generate calibration data sheets in volumetric or mass units, which can be stored for future reference. This capability enhances calibration management programs by providing a record of traceability to recognized calibration standards.
