Product Description PF3W Series 3 Color Display Digital Flow Switch Product Description1. PF3W is a digital flow sensor that constantly monitors water or coolant flow.2. PF3W refreshes the design and operating performance of the legacy PF2W model. The body is up to 40% smaller in volume and requires shorter straight piping for improved installation flexibility.The upgraded 2-screen, 3-color numerical display rotates in both CW and CCW directions, offering improved visibility in a range of orientations.3. Two outputs are available, including two switch signals, or a switch and analog signal.4. Options include a mounting bracket, flow adjustment valve, and temperature sensor to monitor flow and temperature simultaneously.5. PF3W is grease-free, IP65 rated, and C-UL-US, CE and RoHS compliant.Product Feature1. 3-color/2-screen display.2. Integrated display type, Separate monitor type, and PVC piping type.3. Reduced required piping space.4. Rotatable display: Counterclockwise 90°, Clockwise 225°. Display can be rotated in increments of 45° to suit the installation conditions.5. Easy operation, improved visibility. New model PF3W721-14- -M. (Flow rate set from 20-350L/min).Products SpecificationsModelPF3W704PF3W720PF3W740PF3W711PF2A721Working mediumWater and ethylene glycol aqueous solution (with viscosity of 3MPa·s [3 cP] or less)Detection typeKarman vortexRated flow range0.5 to 4L/min2 to 16L/min5 to 40L/min 10 to 100L/min50 to 250L/minDisplay flow range*1)0.35 to 5.5L/min1.7 to 22L/min 3.5 to 55L/min7 to 140L/min20 to 350L/minSet flow range0.35 to 5.5L/min 1.7 to 22L/min 3.5 to 55L/min7 to 140L/min20 to 350L/minSmallest settable increment0.01L/min 0.1L/min 1L/min2L/minConversion of accumulated pulse(Pulse width: 50ms)0.05L/pulse0.1L/pulse0.5L/pulse1L/pulse 2L/pulse Fluid temperature(No freezing or condensation) 0 to 90°C 0 to 70°C Display unit Instantaneous flow: L/min, Accumulated flow: L AccuracyDisplay value: ±3% F.S.

The hold function can be selected. (Intervals of 2 or 5 minutes can be selected.) If the 5-minute interval is selected, the life of the memory element (electronic parts) is limited to 1 million times. (If energized for 24 hours, life is calculated as 5 minutes × 1 million = 5 million minutes = about 9.5 years.) Therefore, if using the hold function, calculate the memory life for your operating conditions, and use within this life. *4) The response time when the set value is 90% in relation to the step input (The response time is 7s when it is output by the temperature sensor.) *5) The response time until the set value reaches 90% in relation to the step input (The response time is 7s when it is analog output by the temperature sensor.) *6) When the temperature sensor is used, it will be AC 250V. *7) When the piping diameter or piping passage is restricted, the specififications may not be satisfified. *8) Products with tiny scratches, marks, or display color or brightness variations which do not affect the performance of the product are verified as conforming products.
