> Models and flow ranges (based on air) Measurement / control system For ranges of700 bar rated MFCs please see our website. * For these models the Multi Gas /Multi Range option is available on request.

IN-FLOW IN-FLOW Air flow ranges Min/Max flow ranges for other gases MFM Model # MFC Model # Minimum/Nominal/Maximum Ar CH4 C2H6 CO 1 Multi Gas/Multi Range option not available for these models > Multi Gas / Multi Range features ♦ Rangeability up to 187,5 : 1 ♦ Flexible, user-programmable ranges and gas types ♦ Easy-to-use configuration software ♦ Multi Gas / Multi Range functionality up to 10 bar; pressure rating up to 100 bar ♦ High accuracy and repeatability

> Notes ♦ Multi Gas / Multi Range is optional on low-flow IN-FLOW series and must be requested at the point of ordering ♦ Extended rangeability for digital communication only; turndown 50:1 when using analog I/O options ♦ The selected orifice of the control valve may limit the rangeability ♦ Standard accuracy (based on actual calibration): ±(0,5% RD + 0,1% FS); ±0,8% Rd plus ±0,2% FS for F-110CI-005/F-200CI-005; ±2% FS for F-110CI-002/F-200CI-002 ♦ Maximum range for gases not mentioned in this list; rule of thumb: nominal range for Air x Conversion Factor; e.g. F-111BI - 1K0: maximum range...

> Thermal mass flow measuring principle The heart of the thermal mass flow meter/controller is the sensor, that consists of a stainless steel capillary tube with resistance thermometer elements. A part of the gas flows through this bypass sensor, and is warmed up by heating elements. Consequently the measured temperatures T1 and T2 drift apart. The temperature difference is directly proportional to mass flow through the sensor. In the main channel Bronkhorst applies a patented laminar flow element consisting of a stack of stainless steel discs with precision-etched flow channels. Thanks to...
