Product Description PF2A Series Integrated type Digital Flow Switch For AirProduct Description1. 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 Feature1. 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.Product SpecificationModelPF2A710PF2A750PF2A711PF2A721PF2A751Working mediumDry Air, NitrogenRated flow range1 to 10L/min5 to 50L/min10 to 100L/min20 to 200L/min50 to 500L/minMininum set unit0.1L/min0.5L/min1L/min2L/min5L/minAccumulated pulse flow rate exchange value(Pluse width:50ms)0.1L/pulse0.5L/pulse1L/pulse2L/pulse5L/pulseDisplay units*1,2)Instantaneous flow rateL/min, CFM×10 -2L/min, CFM×10 -1Accumulated flowL, ft3×10 -1Working temperature0 to 50oCAccuracy*3)±5%F.S.Repeatability±1%F.S.±2%F.S.Temperature characteristics±3%F.S.

(Fixed SI unit [(L/min, or L, m3 or m3×103)] will be set for switch type without the unit switching function.) *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.Analogue Output Part No.Min. rated flow rate valueMax. rated flow rate valuePF2A7101NL/min10NL/min3.5CFM×10-235.0CFM×10-2PF2A7505NL/min50NL/min18.0CFM×10-2176.0CFM×10-2PF2A71110NL/min100NL/min3.5CFM×10-135.5CFM×10-1PF2A72120NL/min200NL/min7.0CFM×10-171.0CFM×10-1PF2A75150NL/min500NL/min18.0CFM×10-1176.0CFM×10-1* When using the analog output of the standard state, please convert according to the following formula.Base state flow rate value ÷ 0.927 = Standard state flow rate value.How to Order Main DimensionsAnalogue Output Product CategoryPackaging & ShippingPackaging type: VPC BoxWhite BoxColor BoxVPC CartonPalletDelivery time:Conventional ProductsCustomized ProductsSpecially Customized Productson the day of payment10 workdays 25 workdaysPayment term:PaypalTTWestern UnionDPLCMoney GramOnline BankPay laterDAYESYESYESNONOYESYESYES YES Transportation:Express (DHL, UPS, TNT, JCEX, FEDEX) is available.Sea and Air transports are available.The most suitable transport way will be chosen for you.Company ProfileFAQQ1: What is your quality assurance?A: We will inspect one by one before delivery.
