Applications
Regardless of whether the liquid is electrically conductive or non-conductive, ultrasonic flowmeters can measure various types of liquids such as potable water, river water, industrial water, agricultural water, wastewater, seawater, and pure water. Materials which allow stable transit of ultrasonic waves such as Carbon steel, Stainless steel, SUS, Castings, Ductile casting, PVC, FRPM, GRP, HDPE, PE, etc.
