Product Application
The explosion-proof vortex flow sensor is based on the Karman vortex street principle and is specifically designed for flammable, explosive, and high-risk working environments. It can achieve high-precision and high-stability flow measurement under harsh conditions. This product is widely used in the following industries for flow measurement and process control:
Petroleum and Chemicals
Suitable for the transportation and process control of crude oil, refined oil, and various chemical media (such as solvents, additives, reaction raw materials, etc.), meeting the strict safety requirements of explosion-proof areas.
Metallurgy and Electricity
Can be used for the flow monitoring of high-temperature blast gas, coke oven gas, compressed air, steam, and circulating cooling water, serving energy management and control in continuous production processes such as smelting and power generation.
Pharmaceuticals and Textiles
Used for precise measurement and ratio control of steam, gas, or liquid (such as medicine, dyes, heat medium) in environments with high safety and cleanliness requirements in pharmaceutical workshops and printing and dyeing production lines.
Water Supply and Gas Supply
Widely deployed in the outlet water of water treatment plants and gas pipelines, as well as the gas supply pipelines of gas stations, to achieve online flow measurement and remote monitoring of urban water supply and gas pipeline networks.
Other industrial pipelines
Can also be applied in the process fluid measurement of industries such as food, papermaking, and building materials, as well as the flow measurement and energy-saving management of various industrial boilers, heat exchange stations, and air compressor stations and other public engineering units.
Thanks to its intrinsically safe or flameproof explosion-proof structure, wide range ratio, no moving parts, and simple maintenance features, the explosion-proof vortex flow sensor has become an ideal flow control and measurement solution for liquid and gas supply pipelines in the petroleum, chemical, and gas station fields.
