ISCO Signature® Flow Meter
Open Channel Flow Measurement

The Signature flow meter is designed for open channel flow monitoring applications. It supports flow measurement technologies including bubbler, non-contact laser area velocity, submerged Doppler ultrasonic area velocity, and ultrasonic. The meter can calculate flow using standard open channel level-to-flow and area velocity conversions, as well as user-defined equations, level to area data points, or level to flow data points, depending on the application need.

The Signature flow meter has unique features to verify data integrity. It logs key events such as changes in calibration and power outages to validate data accuracy. Data can be easily reviewed to detect any type of data alteration. With multiple smart interface options and multi-parameter logging (such as pH), the Signature flow meter provides a common platform for control action, reporting, and communication.

Multiple flow technologies are available so you can select the best flow technology for the measurement site and channel conditions. Available technologies are: bubbler, ultrasonic, continuous wave area velocity, and non-contacting LaserFlow™ velocity.

Acoustic Doppler Flow Meter (ADFM)
Flow Measurement 

The ADFM® Pro20 brings unparalleled flow measurement accuracy to large pipes and channels, delivering flow rate data within 2% of actual value, in flow depths up to 20 feet (6 m). 

Four (4) piezoelectric ceramics in the sensor emit short pulses along narrow acoustic beams pointing in different directions to measure velocity. A fifth ceramic mounted in the center of the sensor assembly, and aimed vertically, is used to measure the depth. 

Each acoustic beam measures velocity at multiple points, known as bins, in the water column. The measured velocity data within each bin are very precise – to within 0.01 ft/s. This distribution of accurate velocity measurements is then used to determine the flow pattern over the entire cross-section of flow. Since the flow pattern and measured velocity distribution are dependent on each other, the ADFM’s advanced flow algorithms automatically adapt to changing hydraulic conditions within the pipe. This removes the need for in-situ calibration and insures accurate flow rate measurement over a host of different measurement environments and hydraulic conditions. 

The ADFM enclosure houses the signal processing, data logging, and data output electronics. The enclosure is available as a NEMA 4X Box housing, suitable for wall or console mounting in permanent applications, and a NEMA 6P cylindrical housing for use in manholes or other “wet” environments.

Isco Non-Contact LaserFlowTM Velocity Sensor

Ultrasonic clamp-on flowmeter

Remotely measures flow in a pipe or channel using advanced technology to measure velocity with a laser beam at single or multiple points below the surface of the wastewater stream. During submerged conditions, flow measurement continues without interruption with an optional Doppler Ultrasonic Area Velocity technology.
