Throttle pressure flow meter measurement accuracy limitations ① middle level in the flowmeter. Because many factors are complex, difficult to improve accuracy. ② narrow range of degrees, since the instrument signal (pressure) and flow rate of the square, only a general range of 3: 1 to 4: 1. ③ site installation conditions are higher. For long straight sections (finger plates, nozzles) Yunnan vortex flow meter quote, generally difficult to meet. ④ throttling device and differential pressure line between the instrument display lead to weakness, prone to leaks, clogging and freezing, signal distortion and other failures. ⑤ pressure loss (finger plates, nozzles). 1m, thus reducing the shortcomings in this regard. Recent years developed a body throttle pressure meter, although there are still impulse lines, but less than the length of the air flow meter is the application of fluid oscillation principle to measure the flow rate of fluid through the vortex flow transmitter in the pipe When, a vortex in the triangular prism alternately occur after the body is proportional to the flow rate of the two columns of the vortex, the vortex of release frequency and fluid flow through the vortex average velocity and vortex shedder body width related features. On the installation conditions, before and after the straight pipe meets the requirements of level between Yunnan vortex flow meter retail, pipeline and meter or vertical, whether or around the pipe to facilitate product maintenance; also taking into account the temperature field in Yunnan vortex flow meter, if there is electromagnetic interference, whether there is vibration. Economically, such as factory line monitoring the flowmeter, to consider reducing the pressure loss, save energy; on the large size of the pipe should be using plug-in air flow meter vortex flow meter Yunnan direct sales, reduce pipeline installation, in order to save costs. Additionally, it should be ensured that the compressed air is clean, so as not to affect the measurement accuracy, the installation of an oil separator and a water separator and other poor quality or measurement of small gas flow when the purification equipment.
