Description

For corrosive and noncorrosive liquids and gases

Useful metering ratios are 10:1 or better. All flowmeters except size 1 may be used with dual float combinations to increase metering to 20:1. Pressure drop is negligible. Flow ranges are linear; low differential pressures are independent of flowrate changes. 

• Heavy-walled borosilicate glass tubes with fused ceramic scales are shock resistant and chemically inert
• Can be used with almost any corrosive or noncorrosive gas or liquid
• Accurate over a wide range of gas and liquid flowrates: from 0.03 to 1812mL/min. for water, and from 2.5 to 60,888mL/min. for air
• Accurate to within ±2% of full scale, with repeatability of ±0.25% of full scale
• Calibration charts for air and water are included; charts for other gases and liquids are available from Bel-Art™ on request at no charge 

Models with aluminum body have 1/8 female NPT connections with plastic hose barb for tubing with 5/16 to 3/8 in. I.D. (8 × 9.5mm) PTFE body units have 3/8 in. O.D. (9.5mm) glass tube extensions.

Note:  Size number (1,2,3, etc.) is a representation of the diameter of the inner glass tube.  The number represents a size type, 1 being smallest and 5 the largest.  Users needing to measure relatively low flow rates or thin gasses would want the lower size number, while those needing to measure relatively high flow rates or thick liquids would opt for the larger size.
