Since the transducers are clamped onto the outside of the pipe, the measurement system is not exposed to any wear, tear or abrasion from the medium flowing inside the pipe and is thus very reliable and durable. Installation requirements are virtually non-existent  - no cutting or welding needs to be done to the pipe and costly process shut-downs are completely avoided.

Moreover, the measurement system does not cause any pressure losses, saving substantial energy costs for the operator.

Measuring at very low but also high pressures, thick pipe walls and exotic materials as well as roughly manufactured pipes is not a challenge at all for FLEXIM's flow meters.

FLEXIM's range of non-invasive flow meters ensure:

100% plant availability

  • Simple attachment of the rugged mounting fixture to the outside of the pipe
  • Installation is possible during ongoing operation without process downtime
  • The measurement system is certified for use in any type of hazardous area environments as well as SIS loops (fulfilling Functional Safety requirements)

100% resistant to media

  • No contact with the flowing media, therefore no wear and tear on the measurement system
  • No need to use expensive special materials as for wetted measurement systems
  • Long-term stable and maintenance-free operation

100% leak-proof and secure

  • No additional risk of pipe leakage caused by the measuring equipment
  • No blockage of small bores or impulse piping
  • No influence of pulsations, vibrations, speed peaks, swirling or cross flows

100% pressure-resistant and robust

  • No pressure limit (from atmospheric pressure with no upper limitation)
  • No extra charge for high pressure ranges
  • Zero point and measurement reading are not affected by pressure changes
  • Unaffected by pressure peaks / surges or solid content in the flow

100% economical and cost effective

  • No pressure loss, assuring low operating costs
  • No scaling costs - one measurement system from 14 inch pipe to 20 foot penstocks
  • Cost-effective installation - no pipe work and no process shut-down required
  • Installation without welding or other mechanical work on the pipe and independent of the pipe dimensions, material and quality
  • Measurement independent of the medium flowing inside the pipe
  • No extra charge for large nominal widths

100% progressive

  • Precise, hysteresis-free, bi-directional flow measurement with high measurement dynamics
  • Long-term stable, drift-free measurement results
  • Measurement at extreme pipe temperature
  • High measuring rate
  • Quick response time
  • Measurement of even minute flows
  • Not sensitive to pulsations, vibrations, velocity peaks, swirling flows or crossflow conditions
