Homogeneous and ultrasonically conductive fluids
(Clean water, waste water, industrial water, river water, sea
water, pure water, etc.)
-4 to 140°F (-20 to 60°C)
Note:
1) above also applicable to ambient temperature
2) For main unit, 14 to 122°F (-10 to 50°C)
10000 mg/L or less
Note) No air bubbles
Pipes made of materials that allow stable transmission of
ultrasonic waves, such as steel, stainless steel, cast iron,
ductile cast iron, PVC, FRPM, etc.
Note) Applicable pipe bores may vary depending on the pipe material
and condition.
1" – 24" (DN25mm to DN600mm)
None, tar epoxy, mortar, etc.
Note) Linings must be closely adhered to the base pipe.
