Thermatel TA2 thermal dispersion mass flowmeters add Foundation fieldbus to the advantages of the standard TA2 model, including dual gas calibration with two unique curves, field adjustability for gas type or mix, calibration verification to reduce downtime and unnecessary recalibrations, internal resettable and non-resettable totalizers, strong signal at low flows and low pressures with high turndown, and ISO 17025 and NIST-traceable calibrations.
