项目投资价值分析报告》通过对塑料管浮子流量计项目所处行业的宏观环境、运行现状、投资情况和发展趋势的综合分析来判断项目投资价值的报告，可为投资者的投资行为提供有力参考。 "2010-2012 China Plastic Tube Float Flowmeter Project Investment Value Analysis Report" A report that judges the project investment value through a comprehensive analysis of the macro environment, operating status, investment situation and development trend of the industry in which the plastic tube float flowmeter project is located. , Can provide a strong reference for investors' investment behavior. The report is based on corporate survey data, China National Bureau of Statistics data and China Customs import and export data. At the same time, in order to ensure that the report is informative, accurate and reliable, and the data are comparable, the report performs necessary screening and grouping of statistical sample data, tightly combines macro sample data and micro sample data, and mainly uses quantitative analysis (including economic statistics). Application of models), a combination of quantitative and qualitative analysis, to deeply dig the inherent laws and potential information contained in the data.

Flow meters are mainly used in chemical, petroleum, light industry, medicine, fertilizer, chemical fiber, food, dye, environmental protection and scientific research departments to measure the flow rate of single-phase non-pulsating (liquid or gas) fluids. Anti-corrosive glass rotor flowmeter is mainly used to detect the flow of corrosive liquids and gaseous media, such as strong acids (except hydrofluoric acid), strong bases, oxidants, strong oxidizing acids, organic solvents and other corrosive gases or liquids Flow detection of media.
安装前，应把仪表内的泡沫支撑物用工具尖嘴钳轻轻把它取出，然后重新把它安装好，在安装时，要注意橡胶垫圈是否装在接管的槽内，以防漏水。 Before installing the plastic tube float flowmeter , the foam support in the instrument should be gently taken out with tool nose pliers, and then reinstalled. When installing, pay attention to whether the rubber gasket is installed in the groove of the pipe. To prevent water leakage.  The interface of the flowmeter can be matched with ABS plastic pipe, or PVC plastic pipe, and connected with special glue, or it can be connected by plastic method, and then connected to the metal flange.  The flowmeter must be installed vertically, without obvious tilt, and its installation height should be convenient for reading the float. When reading, the line of sight and the float should be horizontal. [General standard: The optimal flow rate required is 50% -70% of the maximum flow rate of the flow meter. Try not to use the highest number.  The upstream and downstream inlets and outlets of the meter should ensure a straight pipe section with 5 times the meter diameter.  The pressure of the bedding fluid must be stable. If the fluid is too unstable, it will cause the float to fluctuate and cannot be measured correctly. A buffer or a setter should be set upstream of the flowmeter.  The plastic tube rotor flowmeter should be installed vertically, and the angle between the centerline of the flowmeter and the plumb line should not exceed 5 degrees. 1) When using the meter, first slowly open the upstream valve to full open, and then use the regulating valve downstream of the flow meter to adjust the flow. When the meter is out of use, close the upstream valve slowly, and then close the flow regulating valve downstream of the meter.  The indication value of the meter is seen in the engraved line, and the indication value is read from the scale of the float according to the height of the plastic float flowmeter.  When the cone tube and the float are sticky, they should be cleaned in time.  Regularly check the flowmeter for errors. Once it exceeds the specified error, the float and cone should be replaced or recalibrated to obtain better accuracy. 5] When the measured fluid is inconsistent with the flowmeter's calibration medium, the displayed value must be corrected.
