The LFS series of paddle flow switches have a stainless steel (304 grade) paddle and an IP65 aluminium alloy housing or DIN 43650 connection. These switches are suitable for flow detection in harsh operating environments, where the pipe media is aggressive/corrosive. LFS flow switches can be installed in 1” to 3” bore pipes. Maximum operating pressure is 20 bar and operating temperature range is -30°C to +150°C.

HUANGTONG also offers a range of inline flow switches. These include flow switches for direct pump switching (FSP series), inline flow switches for G1” pipes (FSV10AR series) and inline flow switches for connection to a PLC (FSVPLC series). All inline flow switches provide a turn on flow rate of 0.6 l/min or 3.0 l/min (non-adjustable).
