Several issues to pay attention to when choosing to install and use a pipeline flow meter

  • : 安装取水计量设施是合理测定取水量的一个重要手段,是促进计划用水、节约用水,增强节水意识,加强水资源管理的基础。 Guide : The installation of water metering facilities is an important way to reasonably determine the amount of water withdrawn. It is the basis for promoting planned water use, saving water, enhancing water conservation awareness, and strengthening water resource management. Therefore, the proper selection, proper installation and use of pipeline flowmeters is essential for accurate determination of water withdrawal.
  • With the social and economic development and the increase of urban (town) population, the contradiction between water supply and demand has become increasingly prominent. It is a general trend to build a water-saving society. In addition to enhancing water-saving awareness, technical means are also necessary, such as reasonable selection and correct installation. And the use of pipe flowmeters is essential for the reasonable and accurate determination of water withdrawal.

The installation of water withdrawal metering facilities is an important measure for the reasonable determination of water withdrawal. It is the basis for promoting planned water use, saving water, enhancing water saving awareness, and strengthening water resource management. Therefore, the proper selection, proper installation and use of pipeline flowmeters is essential for accurate determination of water withdrawal.

   正确选择 管道流量计 1 Proper selection of pipeline flow meter

With the development of science and technology and the application of new results, the types of pipeline flowmeters are also changing with each passing day. 10 几种类型。 There are more than 10 types such as electromagnetic flow meters, ultrasonic flow meters, and vortex flow meters . Although various pipe flowmeters have their common features, such as generally requiring full pipe flow, most of them can output standard signals and can also display flow values on the spot, but more have their own characteristics. Such as measurement range, flow rate, measurement accuracy, installation conditions, requirements for water quality, etc. Therefore, it is necessary to comprehensively consider the use conditions and requirements, and select the characteristics of various flowmeters in order to make full use of the characteristics and advantages of the flowmeter to achieve the purpose of application, economy, and convenience.

   根据水流的品质选择管道流量计 1.1 Select a pipeline flow meter according to the quality of the water flow

The quality of the water flow is the first consideration when selecting a flow meter. For example: volumetric flowmeters are generally not suitable for mixed water or sewage; the accuracy of ultrasonic flowmeters will be affected when there is a large amount of sand or large changes in water temperature; external clamps that do not contact the fluid should be selected when measuring corrosive fluid flow Ultrasonic flowmeter or capacitance-inductive electromagnetic meter; turbines, vortex streets, rotary pulp, differential pressure or volumetric flowmeters should not be used when water contains impurities.

   根据流量测量范围及流量变率选择管道流量计 1.2 Select the pipeline flowmeter according to the flow measurement range and flow rate

   )流量计的流量测量范围不仅关系到流量计大小的选择,还关系到流量计的最佳使用条件以及测量精度的保证。 1 ) The flow measurement range of the flowmeter is not only related to the choice of the size of the flowmeter, but also to the optimal use conditions of the flowmeter and the guarantee of measurement accuracy. In general, the selection and design information of the flowmeter will provide the measurement range of a certain caliber flowmeter, and the accuracy of the flowmeter is generally only guaranteed within its inspection curve range. Outside this curve range, the flowmeter can still measure. flow. However, the measurement accuracy decreases, and even the flowmeter is damaged. Therefore, when selecting a flow meter, you should know the flow range of the water pipeline to be measured.

   )流量计的流量变率也是选择流量计时应该考虑的问题。 2 ) The flow variability of the flow meter is also an issue that should be considered when selecting a flow meter. If the water delivery flow rate of the water delivery pipe changes greatly, we can use the measurement range in the volumetric flowmeter, electromagnetic flowmeter and other flowmeters when selecting the flowmeter, because their flow variability is relatively large, which can meet the requirements for use. .
