PF3A712H-F20-FS Applications

The PF3A712H-F20-FS is the highest-capacity model in the PF3A7 H series, measuring air or nitrogen from 120 to 12000 L/min through a G2 port for large trunk lines and compressor room headers. Its PNP switch and 4 to 20 mA analog current output feed both alarms and continuous monitoring, while the external input enables accumulated flow control. The 3-color display and rugged IP65 heating-type sensor resist moisture and debris, ideal for facility-wide compressed air management, energy auditing and leak detection.
