PROPORTION-AIR’S “REAL TIME” FLOW CONTROL Proportion-Air, Inc. F-Series flow monitors ¹ are the heart of Proportion-Air’s new “Real Time²” flow control system. Proportion-Air’s electro-pneumatic controls, which have been a staple of the industry for over 20 years, can be electronically reconfigured to accept feedback from our F-Series flow monitors. This combination of components provides a complete flow control package for flow ranges as low as 2-20 SCFH (0.016-0.16 L/SEC) to 250 SCFM (118 L/SEC). Because the feedback is “Real Time”, the result are a series of flow controllers that respond...

TYPICAL APPLICATIONS SPEED CONTROL QB2 control valve receives feedback from an F-Series flow monitor. By controlling the flow out of the extending cylinder, cylinder speed is controlled SPRAYING & COATING LET’S TALK 317-335-2602 * PROPORTION-AIR * BRFLOW0506E

THE INSIDE STORY OF THE F-SERIES: Response Time < 10ms Analog Output = Measured Flow Analog Differential Pressure Sensor for Real Time Measurement Many Connector Options Pressure Compensated Option Available Venturi Style Orifice No Lead in Pipe Required Available in five Different Pipe Sizes NPT or BSPP Wide range of inert gases No Moving Parts Flow Ranges as low as 20 SCFH & as high as 250 SCFM Mounts in Any Position FUNCTIONAL DESCRIPTION The Proportion-Air, Inc. F-series is a line of flow transducers designed specially to provide real time flow measurement of compressed gasses for many...

Flow (Percent) The Proportion-Air, Inc. F-series product is available in flow ranges from as low as 2 to 20scfh and as high as 25 to 250scfm. Pipe sizes range from ¼ “ to 1 ½”. Both NPT and BSP threads are available. The differential pressure technology incorporated in the Proportion-Air, Inc. F-series flow transducer is ideally suited for rugged commercial and industrial applications. This technology allows measurements of flows from 10% to 100% of the maximum calibrated range. The benefits of real time measurement make the F-series a must in many rapid sequence applications. For example,...

PERFORMANCE CHARACTERISTICS LINEARITY Port Size (inch) O utpu t Signa l [ Volt s ] 50 Maximum Flow (SCFM) This chart shows linear characteristics of the F-series flow monitor with a signal output of 1-10 volts. Characteristics would be similar for 5.6-20 mA units. Port Selection Based on Maximum Flow PRESSURE COMPENSATED GRAPH 5 The pressure compensated graph shows the effect of the pressure compensated model at different pressures. If the supply pressure of the application is constant, a nonpressure compensated model can be used. (see “NONPRESSURE COMPENSATED GRAPH”) Output Voltage...
