Features
Expanded flow range!
Wide range of flow measurement.
Flow ratio*100:1
* Rated flow ratio is 10 : 1 for the current PF2A.
Smallest settable increment: 1 L/min
Current PF2A: 5 L/min (200 L: 2 L/min)
Compact, Space saving
Flow adjustment valve is integrated.
Response time
Can be selected from 50 ms (0.05 s)/ 0.1s/0.5 s/1.0 s/2.0 s
Response time can be set depending on application.
Grease-free
3-Screen Display Digital Flow Monitor New
Allows for the Monitoring of Remote Lines
Piping variations (200 L type)
Reversed display mode
Functions
When the switch is used upside down, the orientation of the display can be rotated to make it easier to read.
Bypass structure
Bypass structure with protruding part at the main piping, reduces the contact of moist air with the sensor, reducing degradation of the sensor and maintaining accuracy.
Digital flow switch to save energy!
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.
Digital display allows visualization of flow rate.
2-color display, Improved visibility
Remote control is possible with accumulated pulse.
