Vortex Flowmeter Application Cases: Steam, Compressed Air, Gas, Chemical, Heating, and HVAC Industries

1. Steam Flow Measurement in Energy Industry

Scenario: A thermal power plant needed to monitor steam flow from boilers to optimize energy efficiency and fuel consumption.

Solution: A DN150 vortex flowmeter was installed in steam pipelines to measure instantaneous flow and cumulative consumption. Temperature and pressure compensation modules automatically corrected for density variations, ensuring accurate mass flow output.

Results: No moving parts enabled reliable operation at up to 400°C and 4MPa. Direct mass flow output eliminated additional density calculations, simplifying system integration and reducing instrumentation costs.

2. Compressed Air Monitoring in Manufacturing

Scenario: An automotive plant needed to track compressed air usage across production lines for energy cost accounting and leak detection.

Solution: A DN80 vortex flowmeter was installed on main air supply lines. 4–20 mA signals were integrated with the plant PLC system for automated energy management and early leak alerts.

Results: Low pressure loss design minimized energy waste. Strong vibration resistance ensured stable measurement in both dry and humid compressed air, reducing unplanned maintenance while improving cost visibility.

3. Natural Gas Distribution in Urban Supply

Scenario: A gas utility required precise flow measurement across medium and low-pressure natural gas distribution pipelines.

Solution: Explosion-proof DN100 vortex flowmeters with built-in temperature and pressure sensors were deployed for standardized volume flow output. Data was transmitted remotely via RTU to the central control room.

Results: Wide turndown ratio (10:1) accommodated significant daily and seasonal flow fluctuations. No regular recalibration required, substantially reducing field maintenance costs across the distribution network.

4. Chemical Liquid Dosing in Process Control

Scenario: A chemical plant required accurate solvent feed control (acetone) for batch reactors, where precision and corrosion resistance were equally critical.

Solution: PTFE-lined DN50 vortex flowmeters were installed for superior corrosion resistance. Closed-loop control with actuated valves maintained dosing accuracy within ±1%.

Results: Ideal for low-viscosity liquids (0.8–30 cSt) with response times under 1 second. The electrode-free design eliminated electrochemical corrosion risks, ensuring long-term stability in aggressive chemical environments.

5. Heating Water Measurement in District Heating

Scenario: A district heating company needed flow data for heat-based customer billing across its hot water distribution network.

Solution: DN200 vortex flowmeters were installed in hot water pipelines, paired with Pt100 temperature sensors for heat energy calculation. Data was transmitted directly to the billing system, eliminating manual meter reading errors.

Results: Withstood high-temperature water up to 150°C with excellent long-term stability. Compact design proved ideal for retrofitting into older pipeline systems with limited installation space.

6. Refrigerant Monitoring in HVAC Systems

Scenario: A central air conditioning system required refrigerant (R134a) flow tracking to optimize cooling efficiency and detect leaks.

Solution: Compact DN25 vortex flowmeters were installed on refrigerant lines, with outputs integrated into the building automation system (BAS) for real-time efficiency monitoring.

Results: Capable of handling gas/liquid two-phase flow. Low power consumption supported battery-powered wireless applications, enabling flexible deployment in existing building infrastructure.
