Detailed Description
V cone flowmeter
overview
V-shaped cone flow measuring throttle device (hereinafter referred to as V cone) is a new kind of differential pressure type flow measuring device, its unique way of side wall gradually shrink throttling, nearly all the shortcomings, change traditional throttling device is differential pressure flowmeter revolutionary results. Its principle is the same as other differential pressure flowmeter, is a classic airtight pipeline and flow continuity principle of conservation of energy principle, and has since the rectifier, self cleaning, self protection performance; Very short straight pipe requirements, no pollution, congestion, can maintain long-term measurement stability; Small cone back-end high-frequency low-rising noise measurement threshold is relatively low, so that the range than 15:1; The pressure loss of the permanent and only 1/3 of the orifice and venturi tube is similar. V cone, therefore, can be widely used in petroleum, chemical industry, the national economy in various fields such as electric power, heat measurement, measurement of liquid and gas media.
Structural characteristics
Low self protection
As a result of the fluid in the cone surface boundary layer effect, make the cone surface protected, cone key size does not change due to abrasion, ensure the long-term stability of the measurement precision.
Low since the rectifier features
Due to the sharp cone in the center of the pipe, forcing fluid to wall annular shrink gradually, so that the flow field after the cone to realize rectifier, without full development also can reproduce the calibration data, real short straight section of the request, the huge advantage is cannot do other flowmeter, revolutionary significance in practical application.
Low self-cleaning properties
Due to the fluid along the cone is accelerated, the dirt can't saved the cone surface impurities; The gases in the liquid or gas and particles in a fluid, fiber, etc., through the cone and be swept downstream pipe crack, there will be no dirt and impurities, block and impact measurement, can guarantee the stability of instrument for a long time.
Low range wider
Because the cone special structure make the negative pressure zone is produced by the high frequency low-rising small noise, relatively orifice the suction pressure disturbance is small, which can be measured the differential pressure signal of smaller, so that the range can be achieved than 15:1.
