SINGLE TUBE FLOW METERS

Product catalog summary
Overview: The document provides detailed information about the Model P and Model Px flow meters, designed for low flow rates and suitable for various applications such as chromatography, manufacturing processes, and laboratory measurements. These flow meters are precision instruments that offer simplicity, versatility, and economy.
Design Features:
  • Rib-guided or fluted metering tubes for stable and accurate readings.
  • Magnifier lens in front shield for enhanced reading resolution.
  • Interchangeability of flow tubes and floats.
  • Non-rotating adapter feature to prevent glass flow tubes from turning during assembly.
  • OPTIGRADTM scales to minimize parallax and eye fatigue.
  • Chemical compatibility and simple panel mounting.
Specifications:
  • Standard accuracy of ±2% FS for most scales, with ±5% FS for specific flow tubes.
  • Calibrated accuracy of ±1% FS optional.
  • Repeatability of ±0.25%.
  • Useful flow range of 10:1 minimum with one float, better than 20:1 with two floats.
  • Maximum operating pressure of 200 psig/13.8 bars and temperature of 250°F/121°C.
Materials of Construction:
  • Flow tubes made of heavy-walled borosilicate glass.
  • Floats available in glass, sapphire, 316 stainless steel, Carboloy®, and tantalum.
  • Mounting fittings in aluminum, brass, or 316 stainless steel.
  • Front shield made of Lexan® with a magnifier lens.
  • O-rings and packing options include Buna-N®, Viton®, PTFE, Kalrez®, and EPR.
Built-in Valves: Meters can be equipped with built-in needle valves (CVTM) or high precision metering valves (MFVTM) with non-rising stems. The placement of valves depends on the type of fluid and service (gas, liquid, or vacuum).
Multiple Tube Flow Meters (Model Px): These meters offer the convenience of multiple tube configurations (2 to 6 tubes) and retain most design features of single tube units. They are suitable for applications requiring metering of several streams of gases or liquids.
Optional Accessories: Various tripod bases are available for different mounting configurations, enhancing the versatility of the flow meters.

SINGLE TUBE FLOW METERS-1

SINGLE TUBE FLOW METERS INTERCHANGEABLE Designed for low flow rates, the Model P flow meter is a precision instrument embodying the inherent simplicity, versatility and economy of the classical rotameter. It is particularly suitable for metering carrier gases in chromatography, indicating and controlling gases in manufacturing processes, liquid and gas measurement in laboratories, pilot plants, flow and level indicating,etc. 150 mm Meter with CVTM Valve Shipped completely assembled, flow meters include standard mounting fittings in a choice of materials, side plates, thick protective magnifying front shield and back plate, optional built-in control valve, and flow tubes selected from the Flow Capacities tables. Panel mounting style is convertible to bench mounting through the use of the optional acrylic tripod. The tripod has a built-in spirit leveler and leveling screws. For multiple tube meters see pages 17 and 18. design features ✓ Rib-guided or fluted metering tubes facilitate stable, accurate readings. ✓ Magnifier lens in front shield to enhance reading resolution. ✓ Interchangeability of flow tubes and floats. ✓ Ease of installation and exchange of flow tubes. ✓ “Non-rotating” adapter feature - glass flow tubes are prevented from turning during the tightening phase of the assembly procedure. ✓ OPTIGRADTM scales minimize parallax and eye fatigue. ✓ Simple means of panel mounting. 17 65 mm Meter with MFVTM Valve WWW.AALBORG.COM - E-MAIL ౧ : [email protected] - PHONE ( 845.770.3000 - TOLL FREE IN U.S.A.

SINGLE TUBE FLOW METERS-2

SINGLE TUBE FLOW METERS BUILT-IN VALVES Select flow tube consistent with requirements from flow capacity tables 6 to 22 (page 55 to 61). Meters are available with built-in needle valves (CVTM), high precision metering valves (MFVTM) with “non-rising stems”, or with no valves. The higher cost of MFVTM valves is justified whenever high sensitivity control and resolution are desirable particularly in conjunction with metering tubes of very low flow rates. Generally, for gas metering it is recommended that valves are positioned at inlets (bottom) for liquids valves may be positioned either at inlets...

SINGLE TUBE FLOW METERS-3

MULTIPLE TUBE FLOW METERS The Model Px multiple tube flow meter line offers, the convenience and simplicity of 2, 3, 4, 5 and 6 tube meters, retaining most of the unique design features associated with single tube units. Multiple tube meters are available with 65mm or 150mm flow tubes same as used in single unit flow meters. Px meters are convenient for applications where several streams of gases or liquids are to be metered in individual channels, or manifolded. Shipped completely assembled, flow meters include standard mounting fittings in a choice of materials, side plates, thick protective...
