Venturi flowmeter is a common flow measurement device widely used in various industrial and experimental fields. Here are eight aspects explaining why the Venturi flowmeter is a reliable solution for achieving accurate flow measurement:

  1. Based on Physical Principles: The Venturi flowmeter utilizes the principles of the Bernoulli equation in continuous flow, generating a pressure differential through contraction and expansion sections in the pipeline to achieve flow measurement. This design based on physical principles provides high measurement accuracy and reliability.

  2. Simple Structure: The structure of the Venturi flowmeter is relatively simple, typically consisting of a long tapered constriction section and two smooth cylindrical sections. This simplicity means it is less susceptible to environmental changes and reduces the likelihood of malfunctions.

  3. No Moving Parts: Unlike some other types of flowmeters, Venturi flowmeters typically have no moving parts. This means they are less prone to wear or damage, thus enhancing their reliability and durability.

  4. Wide Applicability: Venturi flowmeters are suitable for a variety of media, including liquids, gases, and steam. They can be used in various industrial applications such as chemical, petroleum, water treatment, and water supply systems, making them widely applicable across different fields.

  5. Stability: Due to the relatively stable structure of Venturi flowmeters, their measurement results are also stable. Even under different flow and pressure conditions, they can still provide accurate measurement data.

  6. Low Pressure Loss: The design of Venturi flowmeters results in lower pressure losses when measuring fluids. This means they can be used in pipeline systems for extended periods without significantly affecting system operation.

  7. High Accuracy: Venturi flowmeters typically offer high accuracy, providing measurements with precision up to one-thousandth or even one-ten-thousandth. This makes them an ideal choice for applications requiring high-precision flow measurement.

  8. Easy Installation and Maintenance: Due to their simple structure, Venturi flowmeters are usually easier to install and maintain compared to other types of flowmeters. They do not require complex calibration procedures or frequent maintenance, thus reducing operating costs and the workload on staff.

In summary, Venturi flowmeters are a reliable solution for achieving accurate flow measurement due to their design based on physical principles, simple and robust structure, wide applicability, high stability, accuracy, low pressure loss, and ease of installation and maintenance.
