(MW), or density at reference conditions (D@ref) can be used in the plant instead of density at-line conditions. In applications where the process gas is too dirty, too hot, or at too high a pressure, the Sarasota SG901 allows for pre-conditioning of the process stream so a measurement can be made. -

A calibration tee, fitted to the inlet pipe of the density meter assembly, allows for tapping to the calibration valve. The calibration tee facilitates purging and accurate calibration of the pressure transmitter and SG system. Sarasota SG901 User Guide Thermo Fisher Scientific... - Page 17 Operation With the frequency output option, signal outputs from the transducers are fed to a Thermo Scientific Sarasota density converter, which calculates the density (measured), D@ref, SG, and MW of the gas and provides corresponding 4–20 mA current outputs. All variables and calculated values can be displayed on the front panel of the converter.
