GR Series Glass Tube Variable Area Flowmeter
Air ranges from 51 CCM to 66 LPM , water 21 CCM to 2 LPM
DESCRIPTION
Series GR variable area type glass tube flowmeters are ideal for measuring low flow rates of liquids and gases. Standard 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 and a rotating magnifying lens allows a 180° view. Special OEM requirements are welcome.
