I. OVERVIEW

　　Model V Taper Flowmeter is a kind of new differential pressure flowmeter. It can be used to measure variety of liquids, gases or liquid-gas mixed medium. A come which was installed in the pipe measures the flow volume through the different. Pressures between the front frange and the back one. As the geometry figure of the cone has many advantages compared with the traditional differential pressure flow-meter the model V taper flowmeter is composed of three-valve group. Pressure transmitter and accumulator. Temperature and Pressure compensation can be made to form quality-flow measuring system if measuring gas or stream which can model V taper flow-meter is widely used in industries of be compressed.

II. CHARACTERISTICS
