The difference between a vortex flowmeter and an orifice flowmeter

Abstract: The difference information between vortex flowmeter and orifice flowmeter is provided by excellent flowmeter and flowmeter manufacturers. Abstract: In this article, we mainly compare the current technical level and comprehensive performance of vortex flowmeter and orifice flowmeter, and compare these two dimensions, so that we can further understand the difference between the two flowmeters. 1. Vortex flowmeter and orifice flow. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the difference between vortex flowmeters and orifice flowmeters. In this article, we mainly compare the current technical level and comprehensive performance of the vortex flowmeter and the orifice flowmeter, and let us further understand the difference between the two flowmeters. 1. Technical comparison between vortex flowmeter and orifice flowmeter ①. The structure of vortex flowmeter is relatively simple. It is mainly composed of three components: vortex generator, detection element and signal amplifier. The research on the vortex body is quite mature. The vortex body is in the form of a triangular column. At the same time, the vortex flowmeter also has the characteristics of easy installation, high precision, and stable operation for a long time. ②. The technical level of the orifice flowmeter at this stage is still at In order to determine the empirical formula as a basis, in 1980, the International Organization for Standardization merged the two standards of R541 and R781 into the standard ISO5167 (1980); ③, the structure of the orifice flowmeter is also relatively simple, low cost, reliable and other characteristics, the orifice flowmeter It can measure almost all media, and it can be used with differential pressure transmission, which is enough to make up for its own shortcomings; 2. Comparison of the comprehensive performance of vortex flowmeter and orifice flowmeter ①. The device is composed of a differential pressure transmitter, and the conduit needs to have heat tracing measures for the frozen installation. Usually, there are the following problems when using an orifice flowmeter to measure the flow:· It is easy to freeze, easy to block, easy to leak, and heat tracing can easily cause the aging of the differential pressure transmitter device. In some cases, the pressure guiding pipe needs to be added with isolation fluid. The lines are often unequal, resulting in a liquid column difference, which makes the flow indication inaccurate;· The above will change the flow measurement results and cause errors. For example, if the pressure guiding pipe is shortened and installed directly on the pipeline, there will still be a flow dead zone. ② Since the vortex flowmeter has few static sealing points, the flow measurement process will There will be no leakage and dead zone of medium flow, and no heat tracing measures are required for the pipeline, and it is not affected by the pressure, temperature, and viscosity of the medium. Summary: From the comparison of the above two points, it can be concluded that when measuring the same medium, the vortex street The advantages and failure rate of the flowmeter are obviously lower than the failure rate of the orifice flowmeter. This is the reason why the vortex flowmeter can increase the sales by about 30% in the market every year. The above is the whole content of this article. You are welcome to inquire about the flow of our factory. Type selection, quotation, etc. 'The difference between vortex flowmeter and orifice flowmeter'
