工業(yè)環(huán)境中，為了實(shí)現(xiàn)智能制造和連鑄工藝，以前由人來(lái)觀察液位，現(xiàn)在用激光鋁槽液位計(jì)來(lái)檢測(cè)，節(jié)省人力高效

LDM-3R-V激光鋁位計(jì)，液位變送器

It distinguishes itself through high precision as well as high independence from the surface of the measuring object. The red, visible laser beam allows for easy alignment. The sister model LDM-3R-Vhas been further developed for fast distance measurements on white surfaces.
