Advanced laser Doppler technology for non-contacting area velocity flow measurement
The LaserFlow® velocity sensor 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 sensor uses an ultrasonic level sensor to measure the level and determines a sub-surface point to measure velocity. The sensor then focuses its laser beam at this point and measures the frequency shift of the returned light.
The LaserFlow is ideal for a broad range of wastewater monitoring applications. It is compatible with both the Teledyne ISCO Signature Flowmeter, DuraTracker Flowmeter, and the Teledyne ISCO 2160 LaserFlow Module, depending on the type of installation.
During submerged conditions, flow measurement continues without interruption with optional continuous wave Doppler Ultrasonic Area Velocity technology.
With its specially designed mounting bracket in place, the LaserFlow can be deployed and removed from street level. This avoids the risk and expense of confined space entry. A variety of communication options enable programming and data retrieval from a remote location. Information about data quality can be recorded and transmitted with the flow data.
Additionally, built-in diagnostic tools simplify installation, maintenance, and advanced communication options reduce site visits.
For applications within the United Kingdom requiring certification by The Environment Agency, LaserFlow is designated MCERTS Class 2.
