McMillan U802 High Performance Flow Controllers will precisely measure and control flow of virtually any fluid, achieving rates as low as 13 mL/min or as high as 10 L/min. Wetted materials are limited to PTFE, FFKM, and sapphire.
McMillan U802 High Performance Flow Controllers will precisely measure and control flow of virtually any fluid, achieving rates as low as 13 mL/min or as high as 10 L/min. Repeatable results are attained by using a patented microturbine flow sensor design. This design, unlike traditional paddlewheel designs, provides accurate flow measurement with no particle generation. An integrated proportional control valve is utilized to regulate flow rate. PTFE, FFKM, and Sapphire wetted parts ensure compatibility with chemicals commonly found in microelectronics manufacturing processes, including deionized water, CMP slurries, acids, solvents, and photoresists.
Each unit is individually calibrated before shipment, and a certificate of calibration accompanies each flow controller. A repeatability specification of ± 0.2% full scale reassures process engineers of consistent results.
Flow ranges from 13 – 100 mL/min up to 1.0 – 10.0 L/min are available. Consult the factory or authorized representative for custom requirements.
The U802 incorporates a heavy-duty stepper motor to provide fastest response and reliable performance across a large range of differential pressures.
Units operate with 24 VDC power.
Units may be ordered with a 4-20 mA, 0-5 VDC, or 0-10 VDC configuration.
All models have an accuracy specification of ± 1.0% full scale (including linearity).
All units are calibrated at the factory using deionized water. Calibration curves may be requested for fluids with viscosities differing from water.
All units have male flare compatible connections.
All units have an integrated 7-pin connector. Several mating cable options are available.
All units have only PTFE, FFKM, and sapphire as wetted parts.
Male flare fittings are standard.
