Product descriptions from the supplier
PF3w Series 3 Color Display Digital Flow Switch for Water
1. 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 Feature
1. 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).

*1) When the actual flow rate is less than the minimum display flow range, the display will show "0.00", "0.0" or "0 ".
*2) If 0.5s is selected for the response time of the switch output, the repeatability will be ±3% F.S.
*3) Cleared when the power supply is turned off. 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.
