Description

Includes

Metering tube mounted in an aluminum housing, an integral control valve, and two floats (one glass and one stainless-steel; except size 5, which includes one glass and one Carboloy™).

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 x 9.5mm) PTFE body units have 3/8 in. O.D. (9.5mm) glass tube extensions.
