| Abstract: | A new type of vortex shedding flowmeters is presented in this paper , which makesa feature of relatively simple design and highly reliable performance with BST piezoelectric ce-ramic elements as frequency sensors, which can stand to high temperature up to 400 withan insulation impedance of over 1M . A field test started in October 1996 has shown itssatisfactory result. |
