Overview

Series GR is a borosilicate glass tube flowmeter for liquids or gases available in either 65 or 150 mm scale lengths with corresponding reference scales. Direct read scales are also available. Series GR flowmeters can be configured with a standard or precision control valve on either the inlet, outlet or no valve at all; fittings can be specified in either aluminum or stainless steel; O-rings and seals can be provided in Buna-N, Viton® or other optional elastomers.
