Flow Meter GR Series

Glass Tube Variable Area Flow Meter
Air ranges from 51 CCM to 66 LPM , water 21 CCM to 2 LPM

DESCRIPTION

Series GR variable area type glass tube flow meters are ideal for measuring low flow rates of liquids and gases. Standard flow meter units are supplied in 65 mm and 150 mm scale lengths and have arbitrary scales with flow curves (permitting multiple gas and fluid measurements in a single tube). Many direct reading scales are available on request.

Flow tubes are easily changed on the Series GR flow meters, and a rotating magnifying lens allows a 180° view. Special OEM requirements are welcome.
