The FM-1127 Series Flowmeters are offered as a simplified solution to the problem of fluid flow indication at higher flow capacity levels than the FM-1050 and FM-1000 Series Flowmeters. These meters are designed to withstand the physical abuse and environmental corrosion of industrial applications.

A one-piece aluminum channel frame encloses the end blocks, fittings and glass metering element for maximum meter protection and safety.

The precision tapered metering tube has integral float guides to ensure float fidelity. The scale is permanently screened on an acrylic window inset in the meter case which makes it interchangeable for economical alteration of meter applications. A float/scale correlation symbol is marked on the window to eliminate error during application changes. The reading edge of the machined float provides precision read-out delineation. Reading edge instructions are also screened on the scale window.
