Insertion Vortex Flowmeter

Cost-effective flow measurement for large pipes—delivering accurate volumetric data without the expense of full-bore meters.
Designed for large-scale infrastructure, our insertion vortex series features a 1:30 range ratio and high detection sensitivity. By utilizing advanced anti-vibration technology and a built-in sensor structure, it maintains signal integrity even in high-velocity gas and steam applications. It is the high-performance choice for metallurgical and chemical plants seeking to optimize large-pipe flow monitoring.
  • Cost-effective measurement for large pipes (DN300-DN1200)
  • ±2-2.5% acceptable for most industrial applications
  • Ball valve option enables installation without shutdown
  • Retractable design allows maintenance under pressure
  • 60-75% lower than full-bore vortex flowmeters

Large Pipe Measurement at Fraction of Full-Bore Cost

High-performance large-caliber flow solutions designed for minimal energy loss, maximum durability, and simplified maintenance.

Cost-Effective Large Pipe Solution

Specifically designed for calibers ranging from DN300 to DN1200. Unlike expensive full-bore meters, the insertion design offers a high-precision alternative at a fraction of the cost for large-diameter industrial pipelines.

Easy to install and maintain

Equipped with an optional ball valve insertion structure, the sensor can be installed or removed for maintenance without stopping the flow. This eliminates expensive system downtime and ensures uninterrupted process operations.

Advanced Digital Signal Processing (DSP)

Equipped with proprietary Digital Signal Processing (DSP), this meter intelligently distinguishes between true flow signals and mechanical interference. You get stable, reliable readings even in high-velocity steam or high-vibration metallurgical environments.

Energy Efficiency by Design

Our insertion probe is nearly invisible to the flow. By minimizing pressure loss, we help you reduce the workload on your pumps and compressors. It’s a measurement solution that actually pays for itself through lower energy bills.

Durability for Harsh Media

Constructed from premium 1Cr18Ni9Ti stainless steel with no moving parts to wear out, our meters are built to survive. From corrosive chemicals to 350°C superheated steam, this is hardware designed for a 10+ year service life.

Unmatched Integration Flexibility

Whether you are running a standalone site or a fully automated smart factory, we have you covered. With support for 4-20mA, Pulse, RS485 (Modbus), and HART, our meters plug directly into your existing SCADA system for seamless data centralisation.

Understanding Insertion Meter Benefits and Constraints

  • When Insertion is Best Choice:

    • Pipe size DN400-DN1200 where full-bore prohibitively expensive
    • Budget limited—need 60-75% cost reduction
    • ±2-2.5% accuracy acceptable for application
    • Hot-tap installation required (operating systems)
    • Multiple measurement points—cost savings multiply
    • Straight pipe requirements can be met

  • When Full-Bore is Better:

    • Pipe size < DN300 (insertion advantages minimal)
    • Custody transfer requiring ±1% or better
    • Severe flow disturbances (insufficient straight pipe)
    • Bi-directional flow (insertion measures one direction only)
