The VeriCal in-situ calibration verification system for the GF90 air/gas flowmeter enables plant technicians to confirm flow measurement accuracy in minutes without removing the meter from the pipe or process. Validating flowmeter calibration has always been a labor-intensive exercise because meters had to be pulled from the process, returned to the manufacturer or a calibration lab for testing, and then shipped back for re-installation in the process. This system is a specially manufactured and plumbed GF90 flow element with additional electronics to feed and measure a precise flow of gas from a nitrogen source. To test a flowmeter, nitrogen gas is flowed through the meter’s flow element and measured at five pre-set measurement points across the meter’s range. The in-situ flowmeter test data is then compared to original laboratory calibration and installation benchmark test data for the meter.?Fluid Components International, San Marcos, CA; 800-854-1993; www.fluidcomponents.com/Industrial/Products/MassFlowMeters/ProdGF90.asp
