PF2D3, Digital Flow Switch for Pure Water & Chemicals
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.
- Digital flow switch for de-ionized water & chemicals
- Remote type display unit
- Panel mounting
- PNP/NPN open collector 2 outputs
- Unit switching function available
