Flowmeters

Vortex Flowmeter

For steam, gas and liquid measurement in vibration-prone process lines.

Vortex flowmeters measure flow by detecting vortices generated in the flow stream. They are commonly selected for steam, gas and clean liquid service where process conditions, vibration and compensation needs must be checked before model selection.

Steam distribution lines

Compressed air lines

Industrial gas lines

Process liquid measurement

Selection Notes

Conditions to Confirm

A useful quotation starts with the real operating condition, not only the model name.

Media

Steam, Gas, Liquid

Flow range

Share minimum, normal and maximum flow before sizing.

Pressure / temperature

Confirm operating and design conditions.

Pipe size

Send DN, connection type and available straight pipe.

Installation condition

Note vibration, access limits, pipe layout and shutdown limits.

Output / signal

Confirm local display, 4-20mA, pulse, RS485 or other site needs.

Steam and gas configurations

Available configurations can support steam, gas or liquid measurement after checking media, flow range, pressure and temperature.

Options for vibration-prone lines

Vibration-resilient sensor structures can be reviewed for process lines where signal quality may be affected by equipment vibration.

Insertion and large-diameter options

Insertion and large-diameter styles support larger pipelines where a full bore meter body may not be the preferred configuration.
