Flow meters for measuring concentrated sulfuric acid need to have a high degree of corrosion resistance and accuracy to ensure the accuracy of the measurement and the long-term stable operation of the equipment. Here are some flow meter types and recommendations for measuring concentrated sulfuric acid:

Flow meter type

Electromagnetic flow meter (main thrust of sulfuric acid measurement below 98% concentration)

  • Principle: Based on Faraday’s electromagnetic induction principle, it is suitable for measuring the flow of various conductive liquids.
  • Advantages: simple structure, high precision, easy maintenance, and has a stronger adaptability to small traffic.
  • Application scenario: Widely used in metallurgy, chemical industry and other fields, especially suitable for concentrated sulfuric acid (98% concentration below) measurement.
  • Principle: Direct measurement of fluid mass flow meter.
  • Advantages: The mass flow rate of sulfuric acid can be accurately measured, and is not affected by changes in physical parameters such as fluid density and viscosity.
  • Application scenario: It is suitable for high-precision measurement.

Glass rotameter (can measure concentrated sulfuric acid single accuracy is relatively low)

  • Principle: Flow is calculated by measuring the rotation Angle of the fluid in the glass tube.
  • Advantages: Simple structure, intuitive and easy to read.
  • Application scenario: Suitable for low flow, low pressure drop occasions, for concentrated sulfuric acid measurement also has a certain applicability.

Purchase suggestion

  • Consider the concentration of sulfuric acid: different concentrations of sulfuric acid have different requirements for the flow meter, and the concentration range of sulfuric acid should be clear when purchasing to ensure the corrosion resistance and measurement accuracy of the flow meter.
  • Consider temperature and pressure: the temperature and pressure of sulfuric acid will also affect the performance of the flow meter, and the temperature and pressure conditions in actual working conditions should be considered when purchasing.
  • Consider the accuracy requirements: Select the appropriate accuracy level according to the actual needs to ensure the accuracy of the measurement.
  • Consider maintenance costs: Choose a flow meter with a simple structure and easy maintenance to reduce maintenance costs in the later period.
  • Choose well-known brands: Choose flow meters from well-known brands and high-quality suppliers to ensure the quality of products and the reliability of after-sales service.

To sum up, there are various types of flow meters for measuring concentrated sulfuric acid, and various factors should be considered comprehensively when purchasing according to actual needs. Through reasonable selection and use of flow meters, we can ensure the accurate measurement of concentrated sulfuric acid flow rate and long-term stable operation of equipment.
