Measures the flow of ultra-pure water in semiconductor manufacturing plants, paints and coatings in paint processes, water in air-conditioning systems, and irrigation.
Fluids
Homogeneous liquid that accepts the propagation of ultrasonic waves (service water, waste water, industrial water, seawater, pure water, irrigation water, oil, etc.).
The type of measurement
Ultrasonic measurement by transit time difference - 1 channel
Fluid temperature
-40°C to +200°C (depending on sensor used)
Pipe type
FSSA (V method) 25-225 mm
FSSC (V method) 50-600 mm
FSSC (Z method) 600-1200 mm
Plastic (PVC, etc.) *Note 1
Metal (stainless steel, steel, copper, aluminum, etc.)
Note 1 Choose FSSC for the following pipes:
PP pipe with a thickness of 15 mm or more
PVDF pipe with a thickness of 9 mm or more
Coated metal pipe, pipe with internal corrosion, pipe with internal coating (bitumen, Teflon, cement or rubber), or other pipe through which ultrasonic waves have difficulty penetrating.
