Vortex Flow Meters
Vortex flow meters measure steam, gas, and liquid by counting the vortices a fixed bluff body sheds into the flow. There are no moving parts, the pressure loss is low, and with built-in temperature and pressure compensation the meter reports the mass flow of steam. That makes vortex the usual choice for steam and plant gas. Below is our vortex range; pick by medium, line size, and temperature.
Vortex Flow MeterSteam, gas, and liquid. DN15 to DN1000, 1.0% to 1.5%, wafer or flange, with T/P compensation for steam mass flow.
Insertion Vortex Flow MeterVortex on a probe for large ducts, DN150 to DN2000, hot-tap install.
Sanitary Vortex Flow MeterHygienic tri-clamp build for clean steam, gas, and clear liquid, DN15 to DN150.
Precession Vortex Gas Flow MeterGas-only swirl precession meter with onboard temperature and pressure correction to standard volume.
Steam Vortex Flow MeterVortex steam meter with built-in temperature and pressure compensation for true steam mass.
Vortex Compressed Air Flow MeterRobust vortex air meter with temperature and pressure compensation to standard volume, Nm3/h.
Vortex Nitrogen Flow MeterVortex meter for nitrogen, threaded for inerting and blanketing lines, standard volume Nm3/h.
High Temperature Vortex Flow MeterSplit-converter vortex meter for hot lines to 400 C, steam, gas, and liquid.
Choosing a vortex flow meter
All builds share the shedder-bar sensor and the LCD head; the difference is the body, the temperature rating, and the head.
| Build | Use it for |
|---|---|
| Wafer | DN15 to DN300; clamped between flanges, the economical body |
| Flange | Larger lines to DN1000 and higher pressure |
| High-temperature | Hot steam and gas to 400 C |
| Integrated T/P | Steam and gas mass flow without a separate flow computer |
| Insertion | Large air and gas ducts where a full-bore body is impractical |
| Split | Hot lines where the head is mounted away from the body |
FAQ
What is a vortex flow meter best for?
Steam, above all: it reads steam mass flow with built-in temperature and pressure compensation, no moving parts, and low pressure loss. It also measures gas and clean liquid, in one technology.
Is a vortex meter accurate?
It holds 1.0% to 1.5% of rate over a 20:1 range, with a coefficient that does not drift with density or viscosity. It does need 40D and 20D of straight pipe and is sensitive to vibration, so siting matters.
What size and media does it cover?
DN15 to DN1000, for saturated and superheated steam, gas, and clean low-viscosity liquid, in wafer, flange, high-temperature, integrated T/P, insertion, and split builds.
