Abstract:
     The present invention provides a kind of interface sensor capable of satisfying the interface control of both oridinary fluid and specially suitable for the viscous fluid. The liquid interface sensor works as follows: through the screen and non screen in the different density P1>P2 media liquids by the setter of exerting pressure to the piezoelectric crystal, the piezoelectric crystal is made to deliver correspondent low and high potentials, and in accordance with the research and design of fluid kinetic mechanics and fluid viscidity and high molecular surface treatment technology, the adherence of the viscous fluid is made to lower, so that it is specially suitable to viscous fluid.
