Advanced laser Doppler technology for non-contacting area velocity flow measurement

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.

During submerged conditions, flow measurement continues without interruption with the optional Doppler Ultrasonic Area Velocity technology.

With its specially designed mounting bracket in place, the LaserFlow can be deployed and removed from above ground, eliminating unsafe and time consuming confined space entry. A variety of communication options enable programming and data retrieval from a remote location. Information about site conditions can be recorded and transmitted alongside the flow data.

Single- or Multipoint Measurement
Depending on your application needs, the LaserFlow device can be programmed to take velocity measurements at single or multiple points below the water's surface, producing an accurate mean velocity reading.

System Versatility

The LaserFlow's versatile configuration options give you the flexibility to measure flow in most open channel applications. The sensor is compatible with both the Isco Signature flow meter for permanent discharge compliance monitoring, and the Model 2160 LaserFlow module for everything from portable surveys to permanent installations.
