VARIABLE AREA FLOWMETERS
Series 150 and 150K
150 MM, Calibration Chart Referenced, Flowmeters
 The 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.
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. |
