Precession vortex flowmeter requirements for measured airflow conditions

1. The measured gas should be a single-phase, continuous round tube flow through the pipeline.

2, before the gas flows through the flowmeter, its flow rate must be parallel to the pipeline axis, no vortex flow.

3, the air flow should be subsonic, non-pulsating, and its flow rate changes slowly with time.

The measurement principle of the electromagnetic flowmeter is Faraday’s law of electromagnetic induction. It is an instrument that measures the flow of conductive fluids based on the induced electromotive force when the conductive fluid passes through an external magnetic field.

Another important requirement of the electromagnetic flowmeter: how to accurately select the lining material, the lining material of the electromagnetic flowmeter should be selected according to the erosion, wear and temperature of the measured medium.

One key advantage of electromagnetic flow meters is their versatility in handling various fluid types and conditions. Since they rely on the conductivity of the fluid rather than its physical properties, these meters are suitable for a wide range of applications, from clean water to corrosive chemicals. Additionally, they exhibit minimal pressure loss, making them an energy-efficient choice for flow measurement systems.

Vortex flowmeter is a kind of instrument device to measure the flow of pipeline fluid, and it works by the principle of velocity vortex. Vortex flowmeter has two kinds of volume and mass flow measurement, which can be selected according to the situation of the field.

The plug-in electromagnetic flowmeter has a wide range of applications, and can be used to measure the volume flow of conductive liquid and slurry in closed pipelines in many fields such as petroleum, chemical industry, metallurgy, paper making, environmental protection, municipal management, water conservancy construction and so on.

Intelligent vortex flowmeters can measure air. Vortex flowmeter is a new flowmeter for flow measurement based on Karman vortex principle. It has good medium adaptability and can directly measure the volume flow of various media (including air). When measuring air, the vortex flowmeter generates regular vortices through the triangular column vortex generator set in the fluid, and the frequency of these vortices is proportional to the average velocity of the measured medium, so that the air flow can be calculated.

The selection of flue gas flowmeter is a complicated but critical process, which is directly related to the accuracy of measurement results and the reliability of equipment. Here are some of the main factors to consider in the selection process:

Vortex flowmeters are suitable for measuring the mass flow and volume flow of superheated steam, saturated steam, compressed air, general gas, water and low corrosive liquids. We often encounter the following failures in the use of vortex flow meters:

The selection of gas turbine flowmeter can be considered from the following aspects:

One notable advantage of electromagnetic flow meters is their ability to measure bidirectional flow accurately. As the induced voltage is directly proportional to the fluid’s velocity, these meters are highly responsive to changes in flow rates, enabling real-time monitoring and control. Additionally, electromagnetic flow meters are not affected by factors such as temperature, pressure, or viscosity, ensuring consistent and reliable performance across diverse operating conditions. This working principle, coupled with their durability and low maintenance requirements, makes electromagnetic flow meters a preferred choice in industries requiring precise and stable flow measurements.

A liquid turbine flow meter is a type of flow meter designed to measure the flow rate of liquid substances, such as water, chemicals, or petroleum-based fluids. It operates on the principle of a turbine inserted into the flow stream. As the liquid flows through the meter, it causes the turbine to rotate. The rotational speed of the turbine is directly proportional to the velocity of the liquid, allowing for accurate measurement of the flow rate.

In chemical processing plants, vortex flow meters play a crucial role in measuring the flow of corrosive or abrasive liquids. Their resistance to harsh chemical environments, combined with their ability to offer accurate readings even in challenging conditions, makes them valuable assets for ensuring the efficiency and safety of chemical processes. The meters’ capability to handle different fluid types and maintain accuracy contributes to their widespread adoption in chemical industries.
