No matter how challenging the application or site conditions, Teledyne Isco offers a proven technology for your needs.
AV sensors continuously transmit an ultrasonic signal from within the flow stream.
Those signals are reflected off bubbles and particles, and return to the sensor where
frequency shift is measured to derive an average velocity. A differential pressure
transducer in the sensor measures liquid depth to determine the flow area. Flow rate
is then calculated by multiplying the area of the flow stream by its average velocity.
Ceramic crystals transmit acoustic signals (sound pulses) into the flow stream. They
are echoed back after contacting bubbles or particles.
By measuring the difference in frequency between the emitted and returned
signals (known as Doppler shift), the velocities of particles in the flow stream can be
accurately determined.
By “range gating” the returned signals, velocity is measured in multiple, distinct cells,
called velocity bins. Detailed velocity data in relation to sensor location is then used
to calculate a highly-accurate flow profile.
With its sensor mounted above the flow stream, transmitted sound pulses are
reflected off the liquid surface. The elapsed time between transmitted and returned
signals determines liquid level.
Flow rate is then calculated using one of the meter’s built-in flow conversions, or a
user-defined level-to-flow relationship
Especially useful in flow streams affected by harsh weather, debris, or corrosive chemicals, bubbler technology forces compressed air from a submerged tube. The depth of flow is determined by measuring the pressure needed to force the bubbles out of the line. That information is then converted into the flow rate using known parameters.
For sites where wind, steam, foam, or turbulence exist, a probe mounted at the
bottom of the channel measures the pressure of the liquid above to determine
flow stream depth. The level reading is then converted to flow rate using known
parameters.
The LaserFlow 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 water. A non-contacting ultrasonic transmitter measures the liquid head height to determine the wetted area. Multiplying the wetted area by the average velocity yields the flow rate. Flow during surcharge conditions can be measured with an optional, integrally-mounted continuous-wave Doppler area velocity sensor.

Signature® Flow Meter. The Signature flow meter is designed for open channel flow monitoring applications. It supports flow measurement technologies including bubbler, noncontact 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 multiparameter
logging (such as pH), the Signature flow meter provides a common platform for control action, reporting, and communication.

Isco Non-Contact LaserFlow™ Velocity Sensor.
The LaserFlow™ 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. (Patent Pending) The LaserFlow is ideal for a broad range of
wastewater monitoring applications. It is compatible with both the Teledyne Isco Signature Flow Meter and the Teledyne Isco 2160 LaserFlow Module, depending on the type of installation.
During submerged conditions, flow measurement continues without interruption with optional Doppler Ultrasonic Area Velocity
technology.
With its specially designed mounting bracket in place, the LaserFlow can be deployed and removed from above ground, eliminating unsafe and timeconsuming 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 alongside the flow data.

ADFM Velocity Profiling Flow Meters. Isco's ADFM family of flow meters leverage patented ADFM technology, which uses multiple pulse Doppler beams instead of a single continuous wave transmission. As a result, the ADFM obtains highly accurate and precise flow measurement data. Ideal for open channel flow monitoring in non-potable water, ADFM technology delivers exceptional accuracy and precision at sites with difficult hydraulic conditions; no in-situ calibration is required.
