Vortex flowmeters are flow measurement instruments operating on the principle of the Karman Vortex Street Effect. Featuring high accuracy, a wide turndown ratio, low pressure loss, and no moving parts, they are widely used for measuring the flow of various media such as gases, liquids, and steam. Their core application fields and scenarios are as follows:
1. Petroleum and Chemical Industry
As one of the core application fields of vortex flowmeters, this industry uses them for measuring various process media:
- Crude oil and refined oil: Measuring the flow of crude oil, gasoline, diesel, kerosene, and other media in oilfield gathering and transportation, refinery process pipelines, and refined oil storage and distribution links.
- Chemical raw materials and products: Such as methanol, ethanol, ethylene glycol, liquid ammonia, various organic solvents, and acid-base solutions (corrosion-resistant materials required), used for feed measurement, reaction product transportation, and finished product metering in chemical plants.
- Process gases: Measuring the flow of natural gas, liquefied petroleum gas (LPG), hydrogen, nitrogen, carbon dioxide, and other gases to meet the needs of raw material proportioning and waste gas emission monitoring in chemical production.
- Steam: Vortex flowmeters can accurately measure the flow of saturated or superheated steam, which is widely used in chemical plants, for energy consumption accounting and process control.
2. Power Industry
They are mainly used for energy metering and process monitoring in power plants, serving as key instruments for energy conservation and consumption reduction:
- Steam metering: Measuring the flow of superheated steam generated by boilers and exhaust steam from steam turbines in thermal power plants, providing data for unit efficiency calculation and energy consumption assessment.
- Cooling water/circulating water: Measuring the flow of circulating water and cooling water in power plants to ensure the normal operation of equipment cooling systems and conduct water resource consumption statistics.
- Fuel gas/compressed air: Measuring the flow of natural gas, blast furnace gas, and other fuel gases entering boilers, as well as compressed air in auxiliary systems of power plants.
3. Metallurgical Industry
Suitable for measuring media in high-temperature and dusty environments during metallurgical production:
- Blast furnace gas and coke oven gas: Measuring the flow of gas generated by metallurgical furnaces for energy recovery and environmental monitoring.
- Compressed air and nitrogen: Measuring the flow of gases used for purging and protection in metallurgical processes.
- Cooling water and quenching fluid: Measuring the flow of media in cooling systems of metallurgical equipment to ensure safe operation.
4. Water Treatment and Environmental Protection Industry
Used for municipal water supply, sewage treatment, and industrial wastewater monitoring:
- Municipal water supply: Measuring the flow of tap water and reclaimed water in pipe networks for trade settlement by water supply companies and pipe network leakage monitoring.
- Sewage treatment: Measuring the flow of influent, effluent, and return sludge to provide data for sewage treatment process control and compliance with discharge standards.
- Industrial wastewater: Monitoring the flow of industrial wastewater discharge from enterprises, and cooperating with water quality analysis instruments to achieve total quantity control, meeting the requirements of environmental supervision.
5. Food and Beverage and Pharmaceutical Industry
Suitable for measuring clean media and meeting hygienic requirements:
- Liquid raw materials: Such as purified water, fruit juice, milk, and edible oil, used for production batching and finished product metering.
- Steam: Measuring the flow of steam in food sterilization and pharmaceutical sterilization processes to ensure process temperature and time control.
- Compressed air: Measuring the flow of compressed air in clean areas of pharmaceutical workshops to ensure environmental cleanliness.
6. Heating, Ventilation, and Air Conditioning (HVAC) and Building Automation
Used for building energy management and air conditioning system control:
- Chilled water/hot water: Measuring the circulation flow of chilled water and hot water in central air conditioning systems to realize temperature regulation and energy consumption statistics.
- Steam: Measuring the flow of steam in building heating systems for heating cost accounting.
- Compressed air: Measuring the flow of compressed air in building pipe networks to meet the needs of office equipment and processes.
7. Aerospace and Marine Industry
Suitable for measuring media under special working conditions:
- Aviation fuel: Measuring the flow of aircraft refueling and fuel transportation for trade settlement and fuel consumption statistics.
- Marine power systems: Measuring the flow of fuel oil and lubricating oil in marine engines, as well as seawater in cooling systems.
Summary of Application Characteristics
Vortex flowmeters are particularly suitable for scenarios with large pipe diameters and low pressure loss, and have strong adaptability to high-temperature and high-pressure media (such as steam). However, their measurement accuracy is affected by factors such as the Reynolds number of the medium and fluid pulsation, and they perform poorly in measuring low-flow-rate and high-viscosity media (such as heavy oil). Selection should be based on actual working conditions.
