What are the reasons for inaccurate measurement of vortex flowmeters?

The principle of inaccurate measurement of vortex street flowmeter may have the following factors

1. The selection of vortex street flowmeter is generally based on one diameter and one flow range. Therefore, when choosing a vortex street flowmeter, accurate and reliable parameters must be provided in order to select a suitable diameter vortex street flowmeter.

. If the diameter of the vortex street and the pipeline cannot match the stove god, it is recommended to use a variable diameter method to solve the problem.

2、 In the case of flow fluctuations, the flowmeter may experience large fluctuations during measurement. Firstly, when installing the vortex flowmeter, it is necessary to ensure that the installation method is correct in order to ensure the stability of flow measurement.

3、 The influence of accumulation on the upstream surface of the vortex generator in a vortex flowmeter. If there are viscous particles in the measured fluid, they may gradually accumulate on the upstream surface of the vortex generator, causing changes in its geometric shape and scale, and therefore the flow coefficient will also change accordingly. Therefore, attention should be paid to this in application.

2. Little knowledge you dont know about steam flow meters with supervision and inspection certificates

Steam flow meters with supervision and inspection certificates generally refer to vortex street flow meters with TS certificates. The following are some small knowledge about it: Special Equipment Manufacturing License (TS Certification) Definition: The State Administration for Market Regulation supervises and inspects t

he production (including design, manufacturing, installation, renovation, maintenance, etc.), use, inspection and testing of special equipment by relevant units, grants employment permits to qualified units, and grants management behaviors of using TS certification marks.

. Qingdao Hesheng Measurement and Control, a manufacturer that has obtained the Special Equipment Manufacturing License (TS certification), obtained the license in October 2020. With over ten years of R&D and production experience, we are one of the few flowmeter manufacturers in Shandong Province to obtain this certification. Production System: We have an independent instrument production base, a complete production system, a professional R&D and production team, a comprehensive after-sales service system, and abundant products. Product types: There are already intelligent heat network management systems, vortex flow meters, electromagnetic flow meters, ultrasonic flow meters, balance flow meters, intelligent flow integrators, prepaid metering monitoring terminals and other products. The types of steam flow meters (vortex flow meters) with Yingshang supervision and inspection certificates are classified according to the installation method. Flange card type: installation is relatively simple, suitable for some working conditions that require certain installation space and allow card installation in pipeline connection methods. Flange connection type: Connected to the pipeline through a flange, the connection is firm, the sealing is good, and it is suitable for most conventional steam measurement scenarios. Classification of pressure compensation types based on functional characteristics: Considering the impact of steam pressure changes on flow measu
