The V31 series are high quality glass tube variable-area flowmeters (rotameters). This classic design is still the most widely used flowmeter style in the world today. The simple variable-area design makes the flowmeter a perfect choice when ease of installation and operation is a must. The V31 features a tempered glass measuring tube which is inert to most chemicals. This tube is suitable for measurement of both liquids and gases. Liquid flow ranges are available from 0.028-0.28 through 4.4-44 GPM water. Gas flow ranges are available from 0.66-6.6 SCFM through 80-800 SCFM air. Direct reading scales calibrated for process operating conditions are standard. The V31 can be calibrated for viscous media, chemicals, and various compressed gases. The scale will be provided in any measuring units the user specifies when ordering. The standard model is available with NPT threaded, hose barb or flanged connections. Optional adjustable flow setpoint switches are also available. Meters for other specialized applications can always be considered.
