Partially Filled Pipe Flow Measurement

Isco flow meters designed to monitor flow in challenging conditions for applications such as:

  • Wastewater treatment plants
  • Industrial pre-treatment
  • I&I and Billing
  • Surface water and Stormwater monitoring
  • CSO and SSO
  • Full pipe monitoring

No single measurement technology is suitable for all open channel flow monitoring applications. Only Isco offers you a choice of ultrasonic, submerged probe, bubbler, and area velocity flow meters.

LaserFlow™ Non-contact Velocity Sensor

The LaserFlow remotely measures flow in open channels with non-contact Laser Doppler Velocity technology and non-contact Ultrasonic Level technology. The sensor uses advanced technology to measure velocity with a laser beam at single or multiple points below the surface of the wastewater stream.

The LaserFlow is ideal for a broad range of wastewater monitoring applications. It is compatible with both the Teledyne Isco Signature Flow Meter and the Teledyne Isco 2160 LaserFlow Module, depending on the type of installation.

ADFM® Velocity Profiling Flow Meters

The ADFM® product family uses exclusive pulse-Doppler velocity profiling technology to measure the velocity distribution within the flow, delivering advanced flow measurement performance.

This capability makes ADFM flow meters exceptionally versatile - and the most suitable choice for metering sites at large pipes and open channels, particularly those with non-uniform, rapidly changing, backwatered, near zero, zero, or reverse flow conditions.
