Wiring Diagram
Dimensions

What is a vortex flow meter?

A vortex flow meter is a device that measures flow based on the vortex shedding principle. When fluid passes a bluff body inside the meter, vortices are generated, and the frequency is proportional to flow velocity.

What media can this flow meter measure?

It can measure: Water and liquids Steam Air and gases (such as natural gas, nitrogen, compressed air)

What is the measuring principle?

It works based on the Karman vortex street principle. The vortex frequency is directly proportional to flow velocity, which is converted into flow rate by the transmitter.

What are the advantages of vortex flow meters?

No moving parts, low maintenance Stable long-term operation High accuracy Suitable for steam, gas, and liquid Low pressure loss

What is the typical accuracy?

Liquid: ±1.0% Gas / Steam: ±1.5%

What is the installation requirement?

Recommended installation conditions: Enough upstream and downstream straight pipe (commonly 10–20D upstream, 5D downstream) Full pipe flow condition Avoid strong vibration and pulsation

Can it work at low flow or low pressure?

The flow must be high enough to generate stable vortices. If flow is too low, signal may become unstable.

What is the pressure and temperature range?

It depends on model and flange rating, typically suitable for: Medium and high pressure pipelines Wide temperature range for steam and gas applications

What is the power supply and output signal?

Common options: 24V DC power supply Pulse output / 4–20mA output Optional RS485 communication

What is the difference between insertion and pipeline type?

Pipeline type: installed in full pipe systems, higher accuracy Insertion type: suitable for large diameter pipes, easier installation

What pipe sizes are available?

Common sizes include: DN15 to DN300+ (depending on model series)

Does it require regular calibration?

Normally no frequent calibration is required under stable working conditions, but periodic inspection is recommended for critical applications.

Can it measure dirty or impure fluids?

Yes, but excessive coating, scaling, or heavy slurry may affect accuracy.

What is the pressure loss of vortex flow meter?

Pressure loss is relatively low, typically lower than orifice flow meters.
