ANDERSON-MIDWEST Sight Flow Indicators
Inexpensive protection for expensive equipment systems
Anderson-Midwest Sight Flow Indicators are manufactured of quality materials and safety tested to assure long, dependable service at economical prices. Choose female NPT connections (optional BSPP or BSPT) or raised face flanges dimensioned per ANSI 150 lb. Class. For fluids with suspended solids, Model 700 units include two stationary internal wipers. Just rotate the high strength borosilicate glass tube to restore full 360° visibility in seconds without disrupting flow! Quick responding eight blade impeller is sensitive to even very low flows.
