This performance/price advantage was made possible by reducing the
number of mass flow controller parts by almost 50%, automating
calibration around slightly reduced accuracy and leveraging R&D
costs against already developed and proven sensor, valve and LFE
technology. Delivery has been streamlined through stocking the seven
most common flow ranges. The Smart-Trak 50 is designed to deliver
accuracy of +/-1.5% FS, repeatability of +/-0.25% FS, 300 millisecond
response time and 0-50 slpm (nlpm) range in one compact footprint. It
comes with 316L SS wetted materials, field zero and span adjust, analog
outputs as well as RS-232 and RS-485 with optional large local display
and two DB9 connectors.Sierra Instruments Inc.www.sierrainstruments.com800.866.0200
