Specifications

Fluid type
Pipe

Fluid type

Pipe diameter
& material

Detector	Inner diameter	Material
FSSA (V method)	25–50 mm	Plastic (PVC, etc)*1
FSSA (V method)	50–225 mm	Plastic (PVC, etc.)1 Metal (SS, steel, copper, alminium, etc.)2
FSSC (V method)	50–600 mm
FSSC (Z method)	600–1200 mm

*1:: Select FSSC if the pipe material is PP or PVDF.
Allowed pipe wall thickness for FSSA is 15 mm or less if the material is PP, and 9 mm or less if the material is PVDF.
*2:: Select FSSC for metal pipes with coating, pipes rusting inside, pipes lined with coal tar epoxy, Teflon, mortar, or rubber, or other pipes through which the ultrasonic wave is hard to pass.
