Audited Supplier
1. The PF2A is suitable for applications requiring a metered quantity of air, such as for supply confirmation, filling accumulation, or fixed supply consumption.
2. The display can be rotated in 90 degree increments, offering better operation visibility.
3. The thermal sensor is protected in a bypass flow path to reduce contact with moisture and contaminants, avoiding accuracy deterioration and damage.
4. The PF2A has an IP65 ingress protection rating and is both RoHS and CE compliant.
Product Feature
1. Flow rate setting and monitoring are possible with the digital display.
2. Integrated type and separate monitor types are available.
3. Three types of output: Switch, accumulated pulse, and analog outputs.
4. Capable of switching back and forth between cumulative and instantaneous flow.
5. 4-channel Flow Monitor: 4 independent flow rate ranges can be monitored by a single controller.

*2) Flow rate display can be switched between the basic condition of 0ºC, 101.3 kPa and the standard condition (ANR) of 20ºC, 101.3 kPa, and 65% RH.
*3) The piping on the IN side must have a straight section of piping whose length is 8 times the piping diameter or more. If a straight section of piping is not installed, the accuracy may vary by±5% F.S. or more.
*4) Accumulated flow rate is reset when the power supply turns OFF.
*5) Switch output and accumulated pulse output can be selected during initial setting.
*6) Window comparator mode - Since hysteresis will reach 3 digits, keep P_1 and P_2 or n_1 and n_2 apart by 7 digits or more. (In case of output OUT2, n_1, 2 to be n_3, 4 and P_1, 2 to be P_3, 4.)
*7) For details about wiring and thread type, please contact VPC.
*8) Any products with tiny scratches, smears, or display color variation or brightness which does not affect the performance are verified as conforming products.
