A Non-Contact Flow Meter for Open Channel Flow Monitoring

LaserFlow is built on a strong history of water and wastewater monitoring innovations Widest application range. With the breakthrough technology of LaserFlow, the first and only non-contact device to penetrate the water to record velocity, Teledyne Isco has revolutionized the water and wastewater monitoring industry. With the widest level and More than 40 years ago, founder Dr. Allington recognized the need for open channel flow measurement velocity range, the Laserflow is at the time the Clean Water Act of 1972 and the National Pollution Discharge Elimination System (NPDES) suitable for most...

Easy installation and maintenance. The Teledyne Isco hardware makes installation easy. Removal and redeployment is simple from street level. Mounted above the water, the LaserFlow can eliminate confined space entry for maintenance. ca Ease of calibration. Velocity measurement at single or multiple points below the surface eliminates the need for manual profiling. Ultrasonic signal strength validates level measurement while the Doppler power information of the return signal ensures an accurate velocity reading and allows the user insight into changing pipe hydraulics over time. Accurate measurement...

Multiple point velocity measurement Acquire precise readings Single point large pipe Single point small pipe Laserflow, the only non-contact velocity sensor that reads below Eliminate measurement issues in wet environment with optical clarity system the surface, provides maximum precision by taking velocity Eliminate measurement difficulties in moisture-rich conditions. measurements at single or multiple points, producing the Performance is never interrupted, even in less than ideal conditions, most accurate mean velocity reading. Multipoint measurement with the LaserFlow’s advanced optical clarity...

Ease of installation The LaserFlow has error-free calibration, so you can be sure of a precise installation. The distance (d) information from the sensor to water level verifies level calibration, while x-axis and y-axis installation information corrects for marginal error and ensures the LaserFlow is installed correctly. Ultrasonic level signal strength and Doppler power gives continuous assurance of proper installation. Self-learning algorithms & advanced features The LaserFlow sensor is engineered to do the work so you don’t have to. The adaptive focus option enables the LaserFlow sensor to...

Select the right configuration option. From industrial applications to municipal manhole installations, the LaserFlow offers versatile configuration options, giving you the flexibility to monitor flow in numerous open channel applications. For these applications you can use one of three Teledyne Isco flow meters with the LaserFlow: • 2160 LaserFlow Module • Signature® Flow Meter Signature Flow Meter • Signature Portable Flow Meter 2160 LaserFlow Module Battery powered logger to collect historical data • IP 68 enclosure is ideal for installations in manhole and sites with potential to surcharge...

Signature Flow Meter Signature Portable Flow Meter AC powered flow meter for permanent sites Flow meter for battery or solar powered remote sites The flexible platform allows multiple measurement technologies and sampler interfaces with single flow meter Multiple Inputs such as pH, Rain Gauge, SDI 12, Analog, MODBUS, and Contacts provide a common logging and recording platform for different instruments and parameters Recorded parameters can be interfaced with central control system via output/interface such as Analog, MODBUS, Ethernet and/or cell communication The unalterable daily, weekly and/or...

Advanced options for advanced needs. Continuous measurements in submerged conditions Redundant measurement for critical sites During submerged conditions, when water reaches the LaserFlow, the When redundant optional bottom-mounted 350 AV sensor seamlessly takes over the flow measurement flow rate measurement. The surcharge sensor measures velocity us- ing continuous wave Doppler area velocity (AV) technology and level critical monitoring pressure sensor. During surcharged Laser Doppler Velocity Ultrasonic Level sensor can be Submerged LaserFlow Sensor added to the Ultrasonic Doppler Velocity...

Accurate measurement to different elevations In applications such as a free-falling outfall or drop manhole, the level of the water under the sensor will differ from the level at the velocity measurement point. If the difference in elevation is more Remote Ultrasonic Sensor than three inches, a Teledyne Isco remote ultrasonic sensor may Horizontal Mounting Bracket be installed above the velocity measurement point so that both measurement points Sound Pulse reference the same elevation. To accommodate unique Bottom of Channel site requirements, various mounting hardware is available for use with...

Hardware Installation Limit manhole re-entry with sensor retrieval arm Following initial installation and adjustment of the LaserFlow, using the optional sensor retrieval arm, the sensor can be installed or removed as needed without the need for manhole re-entry. Raising and lowering the LaserFlow can be accomplished by grasping the locking handle and removing the sensor from the permanent mounting mechanism. Availability of installation parameters and verifiable measurements ensure exact installment. The handle’s simple, yet effective locking mechanism holds the sensor securely in place and...
