PF2D is a flow switch for liquids including high purity chemicals, solutions, and deionized water.  The PF2D is a remote sensor that sends output to a 4-channel panel monitor capable of reporting up to 4 separate outputs.  Three flow ranges are available, as well as 3 tube size connections.  The monitor displays instantaneous or accumulated flow, as well as an indicator for switch output.  This 4-channel monitor reduces installation, space, wiring and cost.
