Non-contact (non-invasive) ultrasonic flow meters are widely used in various industrial fields: in the food and beverage industry, water and wastewater treatment, agriculture and irrigation systems, water use management in buildings for energy savings, building commissioning and maintenance work (hotels, hospitals, etc.), water parks, swimming pools and aquariums, as well as in the semiconductor industry.
Fluids
Homogeneous liquid that accepts the propagation of ultrasonic waves (service water, waste water, industrial water, seawater, pure water, irrigation water, oil, etc.).
Fluid temperature
-40°C to +200°C (depending on sensor used)
The type of measurement
Ultrasonic measurement by transit time difference - 1 channel
Pipe types and diameters
FSSA (V method) 25-225 mm
FSSC (V method) 50–600 mm
FSSC (Z method) 600-1200 mm
FSSD (V method) 13-100 mm
FSSE (V or Z method) 200-6000 mm
FSSH (V or Z method) 50-400 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.
