This is an inexpensive, 5% accuracy flow meter for liquids or gases. It gives accurate and repeatable indication; and an optional flow switch gives reliable high and/or low flow rate switching. Meter sizes are 1/2, 1, 1-1/2, and 2 inches with capacities to 130 gpm water and 150 scfm air @ STP. Operating range is 10:1.  Scales are 2 to 4 inches long and calibrated in gpm and percent for liquids, percent for gases, or special calibrations. Scales are fused on the tubes or detached and engraved on aluminum. The cast aluminum frame offers 316 stainless. Front and rear tube shields of strong, clear polycarbonate are standard. All other wetted parts are: borosilicate glass; Buna-N, Viton® or EPR O-rings; stainless steel, brass, beryllium copper or polypropylene float materials.

FLOW SWITCH AVAILABLE
This optional, magnetically coupled switch gives reliable high and/or low flow switching. It is easily set to open or close on increasing or decreasing flow. It is compact and easily mounted on the meter. Available in a general purpose or a UL listed hazardous location arrangement.

HIGHER CAPACITIES
Size for size, this meter gives higher capacities; the tapered-float design passes volumes of fluids often double that of other designs.

CONVENIENT TO USE
The tube and float can be removed without tools and without disturbing connections. The meter is designed for easy flush or surface panel mounting
