Bel-Art™ Riteflow™ Mounted Flowmeters
For corrosive and noncorrosive liquids and gases
Supplier: Bel-Art™ H404040010
Alert:
Gaseous hydrofluoric acid may damage the glass.
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™).
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 x 9.5mm) PTFE body units have 3/8 in. O.D. (9.5mm) glass tube extensions.
