PF3W704-SF03-B-N-M Applications

The PF3W704-SF03-B-N-M monitors water or ethylene glycol coolant from 0.5 to 4 L/min through a G3/8 port with an integrated flow adjustment valve for precise setpoint tuning. Twin PNP switch outputs signal high and low flow alarms to a PLC, and the 3-color red/green display gives instant status. Supplied without lead wire (M8 connector) for flexible cabling. Ideal for cooling water verification on welders, molds, spindles and laser sources where reliable low-flow detection protects equipment from overheating.
