所屬品牌美國TYLAN ，性價比較高。擁有3種電接口金手指、15針、9針。較廣應用于半導體行業(yè)。

Autozero Digital Circuitry Automatically resets outputs to zero under no flow conditions, and shifts the entire calibration curve to cancel many effects of temperature coefficients and calibration drift. User-Selectable Response Time Options Offers a quick (0.5 second) step response time in short-cycle processes along with offering a controlled response for long processes. Temperature Coefficients Maintains tight control in varying temperatures Balanced Power Load Low lead current eliminates signal differing from its controlling device Power Operation Insensitive to power supply variations, and will operate within ± 12 volts to ± 18 volts Standard Design Industry standard pinouts and dimensions make the Tylan FC2900 easy to install in many systems

Process Values Designed to meet the exacting requirements of semiconductor processes and equipment, the Tylan FC2900 and FM3900 models are premium quality elastomer-sealed mass flow controllers and meters. These MFCs combine proven components and techniques with innovative concepts in both mechanical and electrical design.
