PF3W7, Digital Water Flow Sensor, 2-Screen 3-Color Display, IP65, 0.5-250 Lpm
PF3W is a digital flow sensor that constantly monitors water or coolant flow. 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. Two outputs are available, including two switch signals, or a switch and analog signal. Options include a mounting bracket, flow adjustment valve and temperature sensor to monitor flow and temperature simultaneously. PF3W is grease-free, IP65 rated, and C-UL-US, CE and RoHS compliant.
- Flow ranges (lpm): 0.5-4, 2-16, 5-40, 10-100, 50-250
- Port sizes (Rc, NPT, G): 3/8, 1/2, 3/4, 1, 1-1/4, 1-1/2 (flow range dependent)
- Temperature rating: 0-90°C
- Output options: NPN/PNP, 1-5V, 4-20mA
- Accuracy: ±3% F.S.
- Repeatability: ±2% F.S.
