VARIABLE AREA FLOWMETERS
Series 150 and 150K

150 MM, Calibration Chart Referenced, Flowmeters

Series 150 Single Tube Flowmeter with Optional BaseplateThe Series 150 & 150K Flowmeters offer precise measurement of gas or liquid flow over a wide range of flow rates at low pressures. Suitable for plant and laboratory use, they are widely used in gas chromatography, atomic absorption spectroscopy and process control. Each flowmeter consists of a replaceable glass metering tube and two standard floats (glass and stainless steel) which expand the range of the flowmeter. The linear scale allows each flowmeter to be used with a variety of gases via a calibration chart (see "Calibration" information box). Tube selection depends on the gas being metered and the range of flow rates required. See Tube Selection Table.

Standard Features
  • Two Floats per Tube (Standard) expand range of flowmeter.
  • Ribbed Tubes stabilize floats and improve accuracy and readability.
  • Borosilicate Glass Tubes allow operating temperatures up to 250°F (200°F for Series 150K).
  • Linear Scale (10-150 mm) allows each flowmeter to be used with a variety of gases via a calibration chart.
  • Threaded Fittings with Locking Nuts (Standard on Series 150) permit front panel mounting.*
  • Unique Valve Design allows bubble-tight shutoff.
  • Availability of Aluminum, Stainless Steel or Kynar®Construction provides a wide material selection for maximum gas compatibility.

* Series 150K Flowmeters may be front panel mounted using predrilled holes on rear of flowmeter and self-tapping screws.

Optional Features
  • Sapphire, Carboloy or Tantalum Floats allow range of flowmeter to be changed without replacing the tube.
  • Baseplate with Leveling Screws permits bench use.
  • Aluminum Bezel permits flush panel mounting.
  • Individual Calibration provides ± 1% of full scale accuracy (±2% on tube No.1).
  • Inlet Filter traps foreign matter, extends flowmeter life and reduces maintenance.
  • High Accuracy Valve with Non-Rotating Stem (NRS) allows very fine adjustments to flow settings.

Calibration

Standard (± 5% accuracy) calibration is performed using Air at normal temperature(70°F) and pressure (14.7 psia). Calibrations for gases other than Air are mathematically derived from the Air calibration. Calibration charts for Air are shipped with each flowmeter or replacement tube. Calibration charts for many other gases and gas mixtures are available at no additional charge. Specify the required calibration charts when ordering. The accuracy of this calibration is ± 5% of full scale.
