ABSTRACT:
A protective shield for the sight glass of a flow meter. The flow meter includes an elongated guard having a slot that houses a sight glass, and a flow indicator carried by a float moves vertically within the sight glass and the fluid flow is read on a scale mounted on the guard and bordering the slot. A transparent open-ended protective sleeve is disposed around the guard and is retained on the guard by a spring clip that extends inwardly of the sleeve and engages an abutment on the outer surface of the guard.
