 Test Methods

  Ceramic ultrasonic transducer, the core element of ultrasonic flow meters, is a liquid-medium sensor. It can be used in liquid flow meter, or as liquid level sensor. Products are made from the piezoelectric ceramic developed by ourselves, has the advantages of better temperature stability and superior piezoelectric effect.

  We have been in the research and development of PZT materials and products nearly 30 years.We are director of Piezoelectric Ceramic Device Specialized Committee, in charge of drawing China’s “The 11th Five-year Plan” and “The 12th Five-year Plan” for development of piezoceramics. Chooosing us will make your developping process earlier and faster.
