Ordering Guide

SMC offers a variety of digital flow switches. Series PF2A for air, PF2W for water, PF2D for deionized water and chemicals. Flow rate setting and monitoring are possible with the digital display. Integrated and remote type displays are available for different types of application. Water resistant construction is used conforming to IP65 protection. Switching from real-time flow rate to accumulated flow is possible.
