PF2W is a digital flow sensor for water or coolant. This is a legacy sensor, refreshed in 2009 as PF3W. This is the remote version of PF2W7, with a display. The mounting bracket is integrated into the body, while the M12 lead wire is optional. PF2W5 can be paired with a PF2W200 or PF2W300 remote monitor to display instantaneous or accumulated flow values. An optional analog output is also
