Semiconductor cleaning tools require accurate flow measurement / control and the ultimate in product purity. Ultrasonic flowmeters such as our M-1500/1600/1700 and digital signal processor based M-2100 meter feature all PFA construction and no moving parts, virtually eliminating the potential for contamination of critical cleaning chemicals. For the ultimate in liquid Flow Control, our MFC-82XX Series are packaged closed-loop flow controllers designed to provide precise flowrate control from as low as 5 cc/minute.
