19 8.1 - SGM VENTURI STD prefabricated channels configuration The SGM-LEKTRA developed in collaboration with the Pavia University Hydraulics Institute a SGM VENTURI STD called venturi channels family. These primary device are Venturi channels with a fl at bottom and they are suitable to be installed in pre-existing rectangular channels. The SGM VENTURI STD are suitable for use in irrigation systems, water treatment, industrial wastewater, for sewage sludge and for any murky waters; the fl at bottom without protrusions has a self-cleaning effect that makes it diffi cult to debris deposit. SGM VENTURI STD can be easily incorporated into existing rectangular channels. To confi gure the fl ow measurement with SGM VENTURI STD channels follow the procedure below: VLW90M - Open channels flow measurement set up guides 8-OPEN CHANNELS FLOW MEASUREMENT SET UP GUIDES With the arrow keys select the TASK menu icon.
