| PFMB | 2～200 5～500 10～1000 20～2000 |
产品特点
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)
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
Allows for the Monitoring of Remote Lines
When the switch is used upside down, the orientation of the display can be rotated to make it easier to read.

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.
● Control of purge air flow of ionizer
● Flow control of the air for spray painting
● Flow control of N2 gas to prevent lead frame oxidation
● N2 blow prevents distortion of camera image due to air turbulence.
● Accumulated indication shows the operating flow rate or residual amount (of N2 etc.) in a gas cylinder.
