Advanced laser Doppler technology for non-contacting area velocity flow measurement
The new ISCO LaserFlow Flowmeter is the first non contact open channel flow meter to use doppler velocity technology with integrated ultrasonic level sensor to measure flows in culverts, sewers and open channels. The LaserFlow uses a laser beam to measure velocities below the water surface at either single or multiple points. The LaserFlow can be utilised as a permanent flow meter when connected to the ISCO Signature flowmeter to provide permanent discharge compliance monitoring.
The flow meter continues to work even in submerged conditions by using the optional doppler ultrasonic area velocity flow sensor.
The ISCO LaserFlow is perfect for a wide range of wastewater flow applications. Installation is both quick and easy with the LaserFlow's specially designed mounting bracket, it is possible to install or remove the sensor from above ground, therefore eliminating the need to enter confined spaces. With external communications protocols it is easy to attach an external wireless telemetry system to retrieve data on a regular basis. As with other ISCO flow meters, it is also possible to retrieve diagnostic data to support the actual flow measurement data.
Single- or Multipoint Measurement
The LaserFlow sets itself apart from any other flow meter with its ability to take velocity measurements at either single or multiple points below the water's surface. Multi-point velocity measurement allows a profile to be deduced and hence provide a very accurate flow measurement calculation.
MCERTS Flow Meter
The ISCO Laserflow is MCERTS certified (Class 2) meeting the Environment Agency's performance requirements. Class 2 MCERTS makes this the most accurate Doppler (non contact or wetted) based flowmeter under the MCERTS scheme for the self monitoring of effluent flow. View downloads for certificate.

The new Isco Signature flow meter is designed for open channel flow monitoring applications. It supports flow measurement technologies including ultrasonic and bubbler. Flow can be calculated using standard open channel level-to-flow conversions, level to flow data points as well as user-defined equations, depending on the needs of the application. Unique features provided by the Signature flow meter help to verify data integrity. It logs key events such as power outages and changes in calibration to validate data accuracy. Stored data can be easily reviewed to detect any type of data alteration.
