Full Description

The Q-Eye PSC MT permanemt velocity area flow meter is designed for applications in full or partially full pipes 100 - 2000 mm (4 - 80 inches) in diameter, or open channels with flow depths 40 - 2000 mm (1,5 - 80 inches)

It uses advanced Doppler profiling technology to directly measure velocity profiles making it the best choice for sites with non-uniform, rapidly changing, backwatered, near zero, negative or everse flow conditions. This eliminates the need for on-site calibration, thereby reducing significantly the cost of installation.

Combined with an integral upward looking ultrasonic or a secondary external depth prseeure sensor (optional) for determining the depth, the meter is using a numerical model for averaged velocity in the entire cross section and the continuity equation to calculate flow. The system can be equipped with up to 4 analog inputs, up to 4 analog outputs, 2 digital outputs and 4 relays.
