Series GR Flowmeters




These precision borosilicate glass flowmeters have interchangeable tube assemblies and include a built-in rotating magnifying strip and 180º viewing angle for easy reading. Two different tube lengths, 65 mm and 150 mm, are available in 18 different air and water flow ranges. Any model may be fitted with one or two floats to increase the operating range. Single float flowmeters have 10:1 turndown ratios, and dual float flowmeters have 20:1 turndown ratio. The GS series has been designed to maintain maximum pressures to 200 PSI and temperatures to 200 ºF.

These flowmeters are fitted with 1/8" FNPT inlet and outlet connections spaced 4 1/2" or 8 13/16" apart. An optional standard cartridge or precision control valve is available.
