System V​ersatility

From industrial applications to manhole installations, the LaserFlow offers versatile configuration options to give you the flexibility to measure flow in most open channel applications. The sensor is compatible with both the Signature flowmeter for permanent discharge compliance monit​​oring, and the 2160 module for everything from portable surveys to permanent installations. Both flowmeters have a variety of communication options for remote data access and programming, eliminating the need for frequent site visits.

Single or Multiple Point 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.

Remote Ultrasonic Option

In applications where the level measurement point of the built-in ultrasonic and the measurement point of the laser velocity are of different elevations, such as a freefalling outfall or drop manhole, the remote ultrasonic option can be used so that both measurement points reference the same elevation.

Due to unique site requirements, various mounting hardware is available for use with the LaserFlow sensor and 310 remote ultrasonic sensor.

Optional Submerged Functionality

During submerged conditions, when water reaches the LaserFlow, the optional bottom-mounted TIENet™ 350 Area Velocity sensor seamlessly takes over the flow rate measurement. The sensor provides ultrasonic Doppler velocity measurement and Differential Pressure level measurement. This option measures flow in the pipe/channel. By measuring velocity over a large area, the ultrasonic Doppler technology provides more accurate flow measurement during submerged conditions.

Optional Redundant Measurement

For redundant flow measurement at critical monitoring sites, a unique flexibility is added by the optional 350 sensor when mounted at the bottom of the pipe. This sensor provides redundant velocity, level, and flow data from the same site as the LaserFlow device.

Easy and Secure Retrieval/Replacement Without Manhole Entry

Following initial installation and adjustment, the sensor can be installed or removed as needed without manhole entry in most situations, using the optional sensor retrieval arm to grasp the handle.

The handle's simple yet effective locking mechanism holds the sensor securely in place, and is easy to engage and release from above ground.
