Digital Flow Switch

3-Color Display Digital Flow Switch for Large Flow PF3A□H(-L)

    ・Applicable fluid: Air, N2
    ・Flow range: Max. 12000 L/min
    ・Flow ratio 100:1
     A wide range of flow measurement is possible with 1 product.
    ・Improved drainage and resistance to foreign matter
    ・Pressure loss: 75% reduction (20 kPa → 5 kPa)
    ・Through bore construction
    ・IO-Link compatible
    ・Can be connected to the air combination (Modular type)
    ・A 4-screen display digital flow switch with pressure/temperature sensor
     (modular type) is available.
     Simultaneous measurement of the (accumulated) flow rate, pressure, and temperature is possible.

Features

Flow ratio 100:1 A wide range of flow measurement is possible with 1 product.

* he flow ratio is 20:1 for the existing model (PF2A7□H/Large flow type).

  • Improved resistance to moisture and foreign matter

    The bypass construction reduces the moist air or foreign matter in contact with the sensor, reducing sensor accuracy deterioration and damage.

  • Through bore construction (Excludes the modular type)

    ・Pressure loss: 75% reduction* (20 kPa → 5 kPa)

    * Compared with the existing model (PF2A7□H/Large flow

    ・Maintenance-free fluid passage

3-color/2-screen display

* 2-screen display: 2-row display of main screen and sub screen

Display rotates 90° and can be reversed.

The display can be rotated in increments of 90° according to the installation. The display can be reversed for easy operation.

  • Smallest settable increment: 2 L/min

    * For the PF3A703H
    * 5 L/min for the existing model (PF2A703H/Large flow type)

  • Grease-free

Application

Flow control of equipment, main line, and branch line

Select a digital flow switch to increase energy savings!

Flow control is necessary for promoting energy saving in any application.
Saving energy starts from numerical control of the flow consumption of equipment and lines and clarification of the purpose and effect.
