Nice video. Best practice, for an Open Channel flow weir application you should set the Cal Lo parameter to be the distance to the bottom of the channel, not the “zero head”. Then, set the zero-head-offset to be the distance from the Cal Lo to the zero-head point (the apex of the notch, or crest height). This will allow the LT500 to accurately detect liquid levels below the notch/crest, and report Head and Flow accurately without loss-of-echo errors. (Small point, coming from someone who is familiar with the Siemens level products.) :)
