The SGM-600P is suitable for measuring flow in partially filled pipes, drainage channels, man-made channels, waterways, drainage ducts, etc. The instrument is composed of a flow calculator, a speed transducer (with a Doppler effect) and level. SGM-600P can display speed, level, flow rate and totalizer. It can record flow and total flow data on an SD card up to 16 GB. SGM-600P can calculate the cross-sectional area of partially filled pipes, open channel or river, and it is possible to input up to 20 coordinate points to describe cross-section of the river or channel with irregular shape. The velocity and level transducer integrates in it the instruments for measuring water speed, depth and temperature. SGM-600P is an indispensable instrument for flow measurement in all those applications where there is no hydraulic projection in the channel or in the pipe.
