Pulse Signal Output: The vortex flow sensor outputs a pulse signal whose frequency is linearly proportional to the actual flow rate of liquids, gases, or steam. Zero drift is minimized, providing highly stable performance. Available in multiple structural forms, including inline and insertion types.
High Accuracy: Provides precise flow measurement, with typical accuracy of ±1.0% for liquids and ±1.5% for gases, suitable for industrial vortex flow meter applications requiring reliable monitoring.
Wide Measurement Range: Covers a broad flow range, with Reynolds number from 2×10⁴ to 7×10⁶, achieving a ratio up to 1:20, making it ideal for diverse steam and liquid vortex flowmeter applications.
Low Pressure Loss: Compared with orifice meters, the vortex flowmeter reduces pressure loss by 25–50%, offering energy-saving operation for industrial fluid systems.
Flexible Installation: Can be installed horizontally, vertically, or at various angles, allowing adaptation to different process pipeline configurations without compromising accuracy.
Anti-Interference and Anti-Vibration: Equipped with advanced anti-interference circuits and a vibration-resistant sensor head, the vortex flow sensor maintains stable performance even in challenging environments.
Non-Linearity Correction: Integrated software automatically corrects the instrument coefficient’s non-linearity, enhancing measurement precision across the full flow range.
EEPROM Data Protection: Cumulative flow data is safeguarded against power interruptions using EEPROM, with data protection lasting over 10 years, ensuring reliable long-term monitoring for industrial vortex flowmeters.
Vortex Flow Meter-Applications
The vortex flowmeter is widely used across various industries for accurate measurement of liquids, gases, and steam. In chemical and petrochemical plants, it ensures precise monitoring of process fluids, supporting safety and efficiency in critical operations. For steam and gas pipelines, vortex flow sensors provide reliable flow measurement under high temperature and pressure conditions.
In HVAC systems and energy management, industrial vortex flow meters help optimize energy usage by accurately tracking airflow and steam consumption. In water and wastewater treatment plants, they monitor the flow of water, chemicals, and sludge, ensuring process control and regulatory compliance. The food and beverage industry relies on vortex flowmeters for sanitary measurement of liquids and gases, supporting quality control and production efficiency.
Additionally, power generation facilities use vortex flow sensors to measure steam and cooling water flow, improving energy efficiency and operational reliability. With versatility across these diverse applications, vortex flow meters are an ideal choice for industries requiring precise, stable, and low-maintenance flow measurement solutions.
Vortex Flowmeters-Measuring Principle
The vortex flowmeter operates based on the Kármán vortex principle, which establishes a direct relationship between vortex shedding and fluid flow. A bluff body, usually a triangular prism, is inserted into the pipeline, creating alternating vortices downstream. The vortex shedding frequency is directly proportional to the flow velocity of steam, gases, and low-viscosity liquids. The industrial vortex flow sensor detects these vortices, and the electronic signal is processed to calculate the fluid velocity and convert it into volume or mass flow rate.
This principle enables vortex flow meters and steam vortex flowmeters to deliver high-precision, reliable, and low-maintenance flow measurement across a wide range of industrial applications. Ideal for chemical, petrochemical, water treatment, HVAC, and power generation systems, these vortex flow sensors ensure accurate monitoring under various process conditions, including high temperatures, pressures, and challenging environments.
Vortex Flowmeter-Structure
The vortex flowmeter consists of a robust flow sensor body made from stainless steel, carbon steel, or specialized alloys, ensuring durability in various industrial environments. A bluff body (triangular prism) is inserted into the flow path to generate alternating vortices for accurate flow measurement. The vortex flow sensor module detects the frequency of these vortices, while the transmitter converts the signal into digital or analog outputs for monitoring and control systems.
Installation options include flanged type for direct pipeline integration and flange-clamp type for easy maintenance or replacement, making the industrial vortex flow meter versatile for different process configurations. Both inline and remote installation designs are available to meet the requirements of diverse industrial applications such as steam, gas, and liquid flow measurement.
