9ES-500V cone differential pressure flow meter of a new device, it is a unique contraction of the wall of the throttle gradually, a throttling device to change the traditional shortcomings of the opportunity it is the differential pressure flowmeter revolution of the results, the principle and the other differential pressure flow meter, is a classic closed pipe flow of energy conservation principle and the principle of continuity, and self-rectification, self-cleaning, self-protective properties. Very short straight pipe requirements, the contamination-free, plug, you can maintain long-term measurement stability, high-frequency low-amplitude cone back the measurement limit of small noise is relatively low, so that the turndown ratio of 15:1, the permanent pressure loss only the orifice of 1 / 3 and Venturi tubes similar, the V-cone flowmeter is widely used in petroleum, chemical, electric power, heating and other industries in the flow measurement and control systems. V-cone flowmeter cutting pieces hanging in the pipeline for a central cone, the cone before the fluid pressure P1 from the undisturbed （ie, not the formation of throttling the fluid to accelerate） the wall; pressure P2 from the cone after the central body, and by means of a lead pipe to the pipe pressure, its pressure and flow is proportional to the square root of ΔP. Calculation and orifice, nozzle and other types.
