Case Studies

Background Mainstream PREMIER Fixed AV-flowmeter was commissioned for measuring flow at a bridge in Sweden with a non-standard profile. The location of the bridge was on a small river flowing a few kilometres downstream from Lake Mien in southern Sweden. There was a requirement to draw a freehand channel section to provide accurate flow measurement. Mainstream was provided with the bridge section dimensions: Mainstream was also provided with an expanded profile of the mounting dimensions for the velocity sensor. Mounting Rail Method Where a freehand drawing requires many coordinates it is advisable to either use a CAD system or draw this [...]
