In industrial production, flow is an important parameter. In order to effectively operate and control the production process, it is necessary to detect the flow rate of various fluids, including liquids, gases, solid particles, etc. Most flow meters have the ability to measure instantaneous flow and total fluid volume accumulation. So how to choose a flow meter for common media applications in production?

Selection of measurement media and flow meters

• Sewage, pulp and other turbid liquid media

Optional flow meter types: mass flow meter, ultrasonic flow meter, electromagnetic flow meter. However, when considering electromagnetic flow meters, it is necessary to consider that the liquid does not contain more air or bubbles;

• Petroleum, diesel and other oil media

Optional flow meter types: mass flow meter, elliptical gear flow meter, turbine flow meter, metal rotor flow meter

• Mortar, two-phase liquid and other large concentrations, solid particle media

Optional flow meter type: mass flow meter, electromagnetic flow meter, optional target flow meter that is too viscous;

• High-flow media such as tap water

Optional flow meter types: mass flow meter, electromagnetic flow meter, vortex flow meter, orifice flow meter, various bar flow meters, etc.;

• Gaseous medium

Optional flow meter types: mass flow meter, thermal gas mass flow meter (excluding water vapor), vortex flow meter, gas turbine flow meter, orifice flow meter, various bar flow meters, etc.;

• Pure water, desalination water and other media with low conductivity

Optional flow meter types: mass flow meter, vortex flow meter, turbine flow meter, ultrasonic flow meter, imported electromagnetism, etc.;

• Strong corrosive media such as acid and alkali

可选流量计类型：抗酸碱内衬&电极的电磁流量计，特殊材质的质量流量计，外夹式超声波流量计;

Influencing factors of flowmeter selection

• Media properties

The density, viscosity, pressure, temperature, and chemistry of the media can affect the performance and longevity of the flow meter. Ensure that the selected flow meter can adapt to the characteristics of the medium to avoid damage or blockage;

• Flow range

Determine the required flow range according to the actual usage situation, and select a flow meter with a suitable range to ensure the accuracy and reliability of the measurement.

• Accuracy requirements

Determine the required level of accuracy based on the application requirements. Different application scenarios have different requirements for accuracy, and choosing the appropriate accuracy level can ensure the accuracy of the measurement results.

• Measurement method

Measurement methods include heat, vibration, differential pressure and other methods. choose the appropriate measurement method according to the specific application scenario;

• Environmental conditions

Consider factors such as operating temperature, pressure, and corrosiveness to choose a flow meter with appropriate materials and adaptability.

When choosing a flow meter, the above factors should be taken into account, and by carefully comparing the scope of application of different flow meters, the type of flow meter that best suits the application is the most suitable for the application. At the same time, it is recommended that users consult professionals or Meitian Group before choosing for more accurate selection advice and technical support.
