1. Selection Tips for Flowmeters

Flow meter selection requires comprehensive consideration of fluid characteristics, instrument performance, installation environment, and economy. Through multidimensional comparison, the most suitable instrument type can be selected. The specific tips are as follows:

1. Clarify the core selection goal. Selection should focus on "meeting measurement needs" and avoid pursuing "perfect" instruments. Due to the complexity of the fluid being tested and the wide variety of instruments, it is necessary to compare multiple types to achieve "strengths and weaknesses", and ultimately choose 1-2 most suitable flow meters.

2. Selection Steps and Techniques: Initial selection of instrument types Based on fluid types (such as gas, liquid, steam, corrosive media, etc.) and five core factors (instrument performance, fluid characteristics, installation conditions, environmental conditions, economy), Chuzhou Dongbu selects 2-3 available instrument types.

. Example: When measuring corrosive liquids, electromagnetic flow meters (corrosion-resistant) or lined turbine flow meters can be prioritized over metal tube float flow meters. Collect data and price information for the initial selection type, including technical parameters (such as accuracy, range, pressure loss), price, maintenance cost, and user cases, to provide data support for subsequent comparisons. Multi dimensional comparison and performance comparison of obsolete instruments: Accuracy and repeatability: For high-precision requirements (such as trade settlement), priority should be given to choosing mass flow meters or Coriolis flow meters; General process control options include turbine or vortex flowmeter.

scenarios where there is a large fluctuation in the volume of the flow tracing chamber (such as pump outlet), instruments with a wide range should be selected (such as vortex flowmeters with a range of up to 20:1). Pressure loss: Low pressure loss instruments (such as ultrasonic flow meters) are preferred for energy sensitive systems (such as large-diameter pipelines). Fluid characteristic adaptation: Temperature and pressure: High temperature and pressure media require the selection of temperature and pressure resistant instruments (such as metal tube float flow meters with a maximum pressure resistance of 40MPa). Viscosity and density: For high viscosity fluids (such as heavy oil), avoid using turbine flow meters and choose between elliptical gear flow meters or volumetric flow meters. Corrosive and abrasive: Corrosive media require lining materials (such as PTFE, PVC) or non-contact instruments (such as electromagnetic flow meters). Optimization of installation conditions: Requirements for straight pipe sections: When space is limited, instruments with low requirements for straight pipe sections should be selected (such as V-cone flow meters that only require 1-3D straight pipe sections). Pipeline diameter: For large-diameter pipelines (DN>300), insertion or time difference ultrasonic flow meters are preferred to reduce costs. Maintenance space: Cleaning ports should be reserved for media that are prone to blockage (such as sewage) to avoid selecting instruments with complex structures (such as waist wheel flow meters). Adaptation to environmental conditions: Electromagnetic interference: In strong electromagnetic field environments (such as near frequency converters), instruments with strong anti-interference capabil
