PF2D20, Digital Flow Switch for 4-Channel Flo-L4eL
SMC offers a variety of digital flow switches. Among them is series PF2D, a digital flow switch for deionized water and chemicals. This series consists of a remote type sensor unit with your choice of a single-channel remote type flow monitor, or a 4-channel remote type flow monitor. Since 4 indicators were previously needed to monitor 4 sensors, the 4-channel monitor reduces the space required for installation.
