Description

The sensor on the 750 module uses patented Doppler technology to directly measure average velocity in the flow stream. An integral pressure transducer measures liquid depth to determine flow area. The 6712 sampler then calculates flow rate by multiplying the area of the flow stream by its average velocity.

The 750 gives you greater accuracy in applications where weirs or flumes are not practical, or where submerged, full pipe, surcharged and reverse flow conditions may occur. With area velocity you don’t have to estimate the slope and roughness of the channel. And Isco’s exclusive 500 kHz Doppler penetrates farther into deep flow streams than 1 MHz systems, whose shorter wavelength can cause them to give “nearsighted” velocity measurement in typical wastewater applications. The Doppler system continuously profiles the flow stream, eliminating profiling and calibration required by electromagnetic systems.

Standard Features
Sealed Area-Velocity sensor resists fouling by oil and grease. Streamlined shape sheds debris.
Choice of standard (10 ft) and extended (30 ft) level measurement range.
During the program’s operation, flow, velocity, and level values are viewable on the sampler's LCD display.
Level and velocity data stored in the sampler are available for later retrieval, reporting, and graphing using Isco Flowlink® software.
Applications
Accurate open channel flow measurement without a weir or flume
Pretreatment Compliance
Stormwater Runoff Monitoring
Permit Enforcement
Sewer Flow Monitoring
Combined Sewer Overflow Studies
Inflow and Infiltration Studies
River and Stream Gauging
