The ST100 Series is the first thermal mass flowmeter to meet new Foundation Fieldbus (FF) H1 standards. Besides FF H1, the flowmeter can quickly be configured to other protocols, including Profibus PA and Modbus, thanks to a plug-in bus communication card. The device also supports analog HART version 7. Designed for monitoring gas flow in various applications, the ST100 features a backlighted readout that simultaneously displays flowrate, totalized flow, temperature and pressure. The display also has a writable field where operators can type in an identification term, and four through-glass touch-activated buttons with extra functionality. The ST100 measures flow with an accuracy of ±0.75% of reading, and is the only flowmeter in its class to offer an option for a pressure transducer, allowing measurement of temperature, pressure and flow with the same probe. The ST100 was developed in response to process engineers’ need for more comprehensive measurement information and for flexibility to adapt to plant technology that might be deployed in the future. The ST100 can store up to five unique calibration groups to accommodate broad flow ranges, differing mixtures of the same gas, and multiple gases. A removable 2-GB micro-SD memory card can store 21 million readings. — Flow Components International LLC, San Marcos, Calif.
