Level Vibration Meter with the Principle of Liquid-fluctuation

Abstract

In this paper,a level vibration meter based on liquid-fluctuation-trigger-switch was designed,fabricated and tested.This device was made up of sensing unit,circuit unit and level adjustment base.The container was composed of two coaxial cylinders.Copper sulfate solution was used as conductive liquid contained.A sound-light electric circuit was used to prompt vibration level.The test results showed that the response time could meet the measurement requirements.
