Gas flow rate calibrator

calGFR is designed for accurate gas flow rate measurement, calibration, heat input calculation and analysis in the field, in the production, or in the lab.

calGFR offers outstanding accuracy and ease of use for calibrating gas flowmeters of various types. The portability feature of this calibrator allows the user to calibrate in a laboratory or to assure the accuracy of production flowmeters in place. The heat input functions replace the manual time observation and related calculations.
