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. This is the remote version of PF3W7, with a display. One or two analog outputs are available, depending on whether the optional temperature sensor is selected. Additional options include a mounting bracket, flow adjustment valve and M8 lead wire. 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: 1-5V or 4-20mA,Accuracy: ±3% F.S.,Repeatability: ±2% F.S.
