Machined Acrylic Flowmeters Precision Glass Tube Flowmeters

Molded Flowmeters

SERIES FR FLOWMETERS SERIES GR & GS FLOWMETERSSeries GR and GS are borosilicate glass tube flowmeters for liquids or gases available in either 65 or 150 mm scale lengths withcorresponding reference scales. Direct read scales are also available. Series GR and GS flowmeters can be configured with a standardor precision control valve on either the inlet, outlet or no valve at all; fittings can be specified in either aluminum or stainless steel;valves can be specified in either brass or stainless steel; O-rings and seals can be provided in Buna-N, Viton® or other optionalelastomers.

Molded with high impact resistant polycarbonate, Series FR6000 and MR3000 are manufactured with precision adjusting valves for accurate leak-free flow control. Molded flowmeters are an economical choice, with high quality.

Series FR are precision-machined acrylic flowmeters with direct reading air and water scales and are available in either English orMetric scales. The Series FR flowmeters can be configured with a control valve on the inlet or no valve at all; fittings and valve canbe specified in either brass, PVC, or stainless steel; O-rings can be provided in Buna-N, Viton® or other optional elastomers.
