LaserFlow Sensors

Whether you're looking for an upgrade from your old sensor, or facing hazardous flow monitoring conditions, Teledyne ISCO has a solution for you. Introducing LaserFlow, the only non-contact flow measurement device to read below the surface. The LaserFlow device can be programmed to take a velocity ​measurement at single or multiple points below the water's surface. We also offer our intrinsically-safe LaserFlow Ex, specifically designed with safety in mind.

​LaserFlow® Non-contact Velocity Sensor

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 and the Teledyne ISCO 2160 LaserFlow Module, depending on the type of installation.

The LaserFlow Ex 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 can be installed in hazardous areas defined as Class 1, Div 1, Zone 0 and ATEX category 1G.

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 Ex is ideal for a broad range of wastewater monitoring applications. With Teledyne ISCO's TIENet Barrier, it is compatible with both the Teledyne ISCO Signature Flowmeter and the 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 Ex 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 its visits.
