Flow Switches – PF3

PF3A7*H, Digital Flow Switch for Large Flow

PF3A7*H, Digital Flow Switch for Large Flow

Series PF3A digital flow switch provides continuous quantitative values as well as switched digital outputs when set flow levels are measured. The PF3A is suitable for applications requiring a metered quantity of air, such as for supply confirmation, filling accumulation, or fixed supply consumption. The oversized PF3A display has 2 screens, with main screen flow values in red or green, while the sub screen settings are shown in orange. The display can be rotated in 90 degree increments, thereby offering better visibility during operation. The thermal sensor is protected in a bypass flow path to reduce contact with moisture and contaminants, avoiding accuracy deterioration and damage.  The PF3A has an IP65 ingress protection rating and is both RoHS and CE compliant.

  • Applicable fluids: Air, Nitrogen
  • Flow ranges: 30-3000, 60-6000, and 120012000 liters/min
  • Rated Pressure: 0.1 to 1.5 MPa
  • Accuracy: +/-3.0% F. S.
  • Accumulated flow to 999,999,999,990 L

PF3W7, Digital Flow Switch for Water, 3-Color Display, Integrated Display

PF3W7, Digital Flow Switch for Water, 3-Color Display, Integrated Display

Series PF3W digital flow switch is perfect for applications requiring a constantly monitored flow of cooling or cleaning water. The PF3W series has been improved both in design and operating performance over the PF2W flow switch.  Depending on the selected model, the PF3W is up to 40% smaller in volume, offering improved piping space and flexibility.  Designed to work with fluids up to 90ºC, these switches incorporate a built-in temperature sensor so both flow and fluid temperature can be effectively monitored at the same time.  Further improvements include the addition of 2 screens, incorporating 3-color numerical displays which can also be rotated in both clockwise and counter-clockwise directions, thereby offering even better display visibility during operation.  Available as non-grease type and with analogue output if required, the PF3W meets IP 65 enclosure protection standards and is both RoHS and CE compliant.
