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.
